Technical Notes › Main Product Parameter String

Main Product Parameter String

The entire main product parameter string (up to 100 characters) is available through the OPSINFO('MAINPRM') REXX function. The OPSPRM REXX function and OPSPARM command processor are restricted to setting and displaying the first 50 characters of this string.

OPSVIEW option 4.1.1 cannot be used to modify the entire MAINPRM string. Only the first 50 characters can be displayed or modified.

Note: The following notes apply to the parameter specified in the product started task JCL procedure:

• The first 7 characters of the parameter string are not considered part of the MAINPRM string since they contain the product subsystem name, the startup member suffix name, and a comma. Blanks following the comma are ignored.
• The parameter string specified through the MAINPRM symbolic parameter in the product started task JCL is logically truncated at the first blank character.
• For example, assuming that MAINPRM has not been modified through OPSPRM/OPSPARM and that the product startup JCL contains:

  MAINPRM='FIRSTPART SECONDPART'
  

  OPSINFO('MAINPRM') would then return the string FIRSTPART.
