CL Programming. CL Programming. The focus of this chapter is ILE rather than OPM. For this reason. 'procedure' is used rather than 'program' for this. However, when the discussion is about CL commands in general. As with other kinds of. CL procedure source statements, compile, and bind. When you enter CL commands as source statements. CL procedure, the source remains for later modification if you choose. This module remains as a. CL procedures ensure consistent processing of groups of. You can perform functions with a CL procedure that you cannot. CL program or procedure. You cannot use all CL. CL source statements, and you can use some of them only in CL. OPM programs. You can determine what restrictions you. Q: Is there a way I can get the attributes (date/time created/modified, file size) for an IFS object in a CL or RPG/IV program? I have a batch file running on an NT. IBM i V5R4 documentation. Welcome to the IBM i V5R4 documentation, where you can find technical information about IBM i. CL commands. You can do this by checking the. If the box does. not contain this indicator, you cannot use the command as source for a CL. IBM has online information about how to read a. Refer to the CL section of the. Programming category in the i. Series Information. Center. To create a program using CL source statements, you must enter. You can then. create an ILE program by compiling the source member into a module and binding. This makes the work station user's job easier and reduces. This reduces the number of commands the. Send a Spool File from AS/400 with a Specific Subject Line and Message Body. Published: May 23, 2007. Hey, Ted: Note: The code accompanying this. PDM or How to Enter Programs. Before you work on this topic, there is an important option to change. From the command line, key in the command STRPDM and hit ENTER. Having discussed how to define files and variables/fields in the new RPG all free, in this post I am going to give examples of how I have code Procedures using the. I have the following code. The program just exits, no value returned from call. AS400System system = new AS400System(); system.Define(ConfigurationManager. Parameters can be passed to CL. CL procedures consist of CL commands. In. most cases, source statements are entered into a database file in the logical. Using the Create Control Language Module. CRTCLMOD) command, this source is used to create a system object. There is a really easy way to do it in SEU: You can use the overlay function to overlay a line with another line. This is useful when one line contains a pattern of. If you're not a subscriber, click here to confirm your subscription now and get free access to AS/400, iSeries, and System i resources. Hey its seems to be exciting but its true. The. created CL module can be bound into programs. A CL module contains one. CL procedure. Other HLL languages may contain multiple procedures for. Using the Create Program (CRTPGM) command, this. Security - Reference. The following example shows the basic parts of. The input is submitted to a job. Submit Diskette Job (SBMDKTJOB) command. The input. stream should follow this format. CRTBNDCL PGM(QGPL/EDUPGM) SRCFILE(PERLIST). DATA FILE(PERLIST) FILETYPE(*SRC). If you want to. keep the source inline, a Copy File (CPYF) command could be used to copy the. The program could then be created using. The IBM- supplied. QDKTSRC (use QTAPSRC for tape). Assume, for. instance, that the CL source statements are in a source file on diskette named. PGMA. To create the CL module based on the source. CRTCLMOD MODULE(QGPL/PGMA) SRCFILE(QDKTSRC). When the CRTCLMOD command is processed, it treats the QDKTSRC source file. Using the override, the source is. PGMA is created in QGPL, and the source for that. The declare commands must precede all other commands except the. PGM command. This. Accessing Objects in CL Programs, and in the sections discussing various objects. In. some circumstances, for your procedure to run successfully, you may. A display file. Use display files to format information on a device. If your procedure uses a display, you must enter and create. Create Display File (CRTDSPF). You must declare it to the. DCL section by using the Declare File (DCLF) command. Records in a database file may be read by a CL. If your procedure uses a database file, the file must be. Create Physical File (CRTPF) command or the Create Logical. File (CRTLF) command before the module is created. You can use Data. Description Specifications (DDS), Structured Query Language (SQL), or. IDDU) to define the format of the records. The file must also be declared to the procedure in the DCL. Declare File (DCLF) command. See Working with Files in CL Procedures for more information. If you use a CALL command, the called program must. CALL command. It does not have to exist when. See Accessing Objects in CL Programs and Chapter 3, . If you use the CALLPRC command, the called. CRTPGM is run. It does not have to. CRTCLMOD is run. To. A, B, and C, for example), you can. CL procedure STARTUP with the following code. PGM /* STARTUP */. In this example, the Programmer Menu is used to create the program. You do not have to change any other information. If you attempt to run this sample program, however, the. CALL commands are run. These can be. IBM- supplied or commands defined by you. You cannot use some. IBM- supplied commands in CL procedures. IBM has online information. CL. procedures. Refer to the CL section of the. Programming category in the i. Series Information. Center. Commands that can only be used within CL procedures cannot be. RQSDTA or CMD parameter. You can use this list to select the appropriate command for. IBM provides online information on how to. Refer to the CL. section of the Programming category in the i. Series Information. Center for this information. Familiarity with the function of. Superscript 1 indicates the commands that you can use. CL programs and procedures. Each of the following uses is described in greater detail. In general, you. Use variables, logic control commands, expressions, and built- in functions. CL procedure. DCL & C *LGL. DCL & A *DEC VALUE(2. DCL & B *CHAR VALUE(ABCDE). CHGVAR & A (& A + 3. IF (& A < 5. THEN(CHGVAR & C '1'). DSPLIB ('Q' . The following illustration shows how control can be. CL procedure and RPG IV* and ILE COBOL procedures in an. To use the application, a work station user would request. A, which controls the entire application. The illustration. The preceding example shows a single bound program (PGMA) that is. CALL command with PGMA. PGMA consists of. A CL procedure (PGMA) calling an RPG IV procedure (PGMB). An RPG IV procedure (PGMB) calling another RPG IV procedure (PGMC). An RPG IV procedure (PGMB) calling a CL procedure (PGMD). A CL procedure (PGMA) calling an ILE COBOL procedure (PGME). An ILE COBOL program (PGME) calling a CL procedure (PGMF). The procedures can be created as indicated in the following example. IBM. provides online information that explains the syntax rules for writing. Refer to the CL section of the. Programming category in the i. Series Information Center. A variable is a named changeable value that can. Variables can be used. CL commands. When a CL. Every. time the command is run, a different value can be substituted for the. Variables and expressions can be used as parameter values. CL procedures and programs. The use of variables as values gives CL programming a special. You might, for instance. CL procedure to direct the processing of other programs or the. The system identifies these as variables. CL procedure. You can define (specify) the value of the. CL procedure. Defining it is accomplished using the Declare CL. Variable (DCL) command and consists of defining the attributes of the. The attributes are type, length, and initial value. If your CL procedure uses a file, you must specify. FILE parameter on the Declare File (DCLF). The file contains a description (format) of the records in the. During compilation, the DCLF. CL variables for the fields and indicators defined. The variable has the same name as. Command parameters, however. CL procedure through the use of the. See Allowing User Changes to CL Commands at Run Time for more information. See Using the QCAPCMD Program and Using the QCMDEXC Program for more information. The first character following the & must be. For example. The CL variable value must be one of the following. A character string as long as 5. A. logical variable must be either '0' or '1'. For type *CHAR, if you do not specify the LEN parameter. For example, the Change. Library List (CHGLIBL) command requires a list of libraries on the LIBL. The elements in this list can be. CHGLIBL LIBL(& LIB1 & LIB2 & LIB3). When variables are used to specify elements in a list, each element must be. DCL VAR(& LIB1) TYPE(*CHAR) LEN(1. VALUE(QTEMP). DCL VAR(& LIB2) TYPE(*CHAR) LEN(1. VALUE(QGPL). DCL VAR(& LIB3) TYPE(*CHAR) LEN(1. VALUE(DISTLIB). CHGLIBL LIBL(& LIB1 & LIB2 & LIB3). Variable elements cannot be specified in a list as a character. Incorrect: DCL VAR(& LIBS) TYPE(*CHAR) LEN(2. VALUE('QTEMP QGPL DISTLIB'). CHGLIBL LIBL(& LIBS). When presented as a single character string, the system does not view the. The program and library name cannot be specified in one. Incorrect: DCL VAR(& PGM) TYPE(*CHAR) LEN(1. CHGVAR VAR(& PGM) VALUE('MYLIB/MYPGM'). DLTPGM PGM(& PGM). Here again the value is viewed by the system as a single character string. If a qualified name must. SUBSTRING and the *TCAT concatenation function to assign. See Using the %SUBSTRING Built- In Function and Chapter 9, . For instance, if you wanted. DCL VAR(& LIB) TYPE(*CHAR) LEN(1. VALUE('*LIBL'). DLTPGM & LIB/MYPROG. However, it would be incorrect to specify the VALUE parameter. DCL VAR(& LIB) TYPE(*CHAR) LEN(1. VALUE('*libl'). Note that if this VALUE parameter had not been enclosed in apostrophes, it. This error frequently occurs. REMEMBER: Relying on. Where this is true, you can also use character. Some. types of values are required for parameters. If the parameter allows. INT2, *INT4. *UINT2, *UINT4, or *DEC) and also allows reserved values (a character string. The variable must be declared as TYPE(*CHAR) if you intend. Because both the number and the. CL procedure that. JOBSEP value. DCL & NRESP *CHAR LEN(6). DCL & SEP *CHAR LEN(4). DCL & FILNAM *CHAR LEN(1. DCL & FILLIB *CHAR LEN(1. DCLF... The variable & NRESP is a character variable manipulating. The JOBSEP. parameter on the CHGOUTQ command will recognize these values as if they had. The DDS for the display. VALUES keyword to restrict the user. IGNR, NONE, NORM, or SAME. The CL section of the. Programming category in the i. Series Information Center. The value can be changed. To a constant. CHGVAR VAR(& INVCMPLT) VALUE(0). CHGVAR & INVCMPLT 0. INVCMPLT is set to 0. For example, the following commands blank out 1. CHGVAR %SST(*LDA 1 1. CHGVAR & A %SST(*LDA 1 1. For a logical variable, the value to which the variable is to be changed. For decimal variables, a decimal or character. For character variables, either character or decimal. The length and. decimal positions of & B are 5 and 2, respectively. The current. value of & B is 1. The resulting value of & A is.
