Hi,
Can anybody please explain the option PLIXOPT used in PL/1 codes. I know that it is used for setting run-time options. But I want to know that in details. I also want to know what all other options can be used to pass in PLIXOPT.

arnabis2good,
The PLIXOPT variable can be used to specify storage management options and overrides to the default run-time options which have been established for your installation.
PLIXOPT is an external static varying character string. It should contain a list (separated by either blanks or commas) of storage and run-time options to be overridden.
to request an Initial Storage Area of 20K for Automatic Storage Variables and a Storage Management Report to analyze the use of the ISA and other execution time storage areas. The procedure coded with OPTIONS(MAIN) is the appropriate place to declare PLIXOPT.
Run-time options can be specified in a PL/I source application by means of the following declaration:
Code:
DCL PLIXOPT CHAR(length) VAR INIT('string')
STATIC EXTERNAL;
where string is a list of options separated by commas or blanks, and length is a constant equal to or greater than the length of string. Run-time options in PLIXOPT are parsed by the compiler. If more than one external procedure in a job declares PLIXOPT as STATIC EXTERNAL, only the first link-edited string is available at run time.
If the PLIXOPT string is specified in an OS PL/I main procedure, the options in the string are processed as if specified in the CEEUOPT CSECT. However, mixing a user-provided CEEUOPT with PLIXOPT is not recommended.
Each time a PL/I application runs, the default run-time options established at installation time apply unless overridden by a PLIXOPT string in the source program or in the PARM parameter of the EXEC statement. Options specified in the PARM parameter override those specified in the PLIXOPT string.
