Tom, PMFJI here but the limit with PARMDD is 32K I believe. JES/JCL limit is 100, not 255. The COBOL questions is, does the compiler correctly process PARMDD input > 255 characters, and if so which version(s)? Only V5+? I could understand V4 not supporting it, but not V5+.

Someone else asked what the COMPILER limit for reading the PARM= options string is, but there is none. There is a JCL/JES limit of 255 bytes. There is no limit for SYSOPTF (using OPTFILE). It seems pretty clear that we cannot change the default behavior to read SYSOPTF whenever it is present, regardless of OPTFILE, so we will probably add another (sigh) compiler option >There is nothing to prevent a user or product to go ahead and use >PARMDD, and it could point to the program's (compiler's) specific >overrides. The program (compiler) can only read the PARM for the >length it specifies (100/255) until modified to allow a parm length of >32K. Maybe a couple releases down the road you can give a warning >message that the program (compiler) specific parm will be removed. -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
