Defining a compiler-option data set (SYSOPTF)
Define a data set that contains the compiler options for
your COBOL program by coding the SYSOPTF DD statement
as shown below.
About this task
//SYSOPTF DD DSNAME=dsname,UNIT=SYSDA,VOLUME=(subparms),DISP=SHR
To use a compiler-option data set, specify OPTFILE either
as a compiler invocation option or in a PROCESS or CBL statement
in your source program.
Within the
SYSOPTF data
set: - Specify compiler options in free form between columns 2 and 72,
using the same syntax as you use for invocation options or for compiler
options in a
PROCESSorCBLstatement. - Code an asterisk (
*) in column 1 to cause a line to be treated as a comment. - Optionally code sequence numbers in columns 73 through 80; those columns are ignored.
You can optionally place the compiler options directly
in the input stream after the SYSOPTF DD statement
if you compile using the OPTFILE option:
//COB EXEC PGM=IGYCRCTL,PARM='OPTFILE'
//SYSOPTF DD DATA,DLM=@@
SSRANGE ARITH(COMPAT)
OPTIMIZE

//SYSIN DD . . .
You can concatenate multiple SYSOPTF DD statements
if you have multiple compiler-option data sets:
//SYSOPTF DD DSNAME=dsname1, . . .
// DD DSNAME=dsname2, . . .
Compiler options that are in later data sets in the concatenation take precedence over options in earlier data sets in the concatenation.
