Syntax

call script-file [parameter-name=parameter-value]...

Description

The call command loads and executes a command script.

Scripts are interpreted line by line, with parameter substitution made just before each line is executed. Parameter substitution is indicated with a $(PARAMETER_NAME) sequence in the called script. Parameters are replaced by the value corresponding with the parameter's name (name=value format) in the call command itself. Each parameter of the call command must have a corresponding value.

call commands can be nested in called scripts up to ten levels deep.

If a parameter with the same name appears more than once in call, the first instance of the parameter with that name is used. If a parameter is referenced in the script, but was not passed in via the call command, an error is issued when the line with the reference is parsed.

Parameters

Parameter

Description

script-file

Filename of the script to process.

parameter-name

Name of a parameter to pass to the script.

parameter-value

Value to be set for the parameter.

Examples

To invoke a script called script.udm.

  • Parameter file has a value of *.
  • Parameter src has a value of c:\source.
  • Parameter dst has the value /etc/dest.
call script.udm file=* src=c:\source dst=/etc/dest


To invoke a script under IBM i, the member name is required and can be *FILE:

call mylib/myfile(myscript)

Specifying *FILE invokes the normal default IBM i file search order.


To invoke a script under IBM i included as an inline file in a database job, the call must specify *FIRST as the database member name.

The following example illustrates both:

  • Invocation of an inline script, CALLME, using the STRUDM command from a database job.
  • Invocation of an inline script, CALL1, using the CALL command from a database job.
//BCHJOB JOB(testcall) ENDSEV(10) OUTQ(mytest/UDMOUTQ) LOGCLPGM(*YES)
LOG(2 20 *SECLVL) MSGQ(*USRPRF)
//DATA FILE(CALL1) ENDCHAR(ENDDATAFILE)
print msg="I made it to call1 - an inline file"
ENDDATAFILE
//DATA FILE(CALLME) ENDCHAR(ENDDATAFILE)
OPEN S=AS400V5 USER=qatest PWD=***** PORT=4311
CALL CALL1(*FIRST)
CLOSE
ENDDATAFILE
STRUDM SCRFILE(CALLME)
//ENDBCHJOB
