Rules for the user-defined variables created in LOADPLUS user exits

The LOADPLUS user exits return user-defined variables that you can use with the DSNPAT installation or command option to construct data set name patterns.

LOADPLUS uses these patterns and the values that are returned for any user-defined variables to create data set names during dynamic data set allocation.

The following rules apply when using a user-defined exit routine to create your variables:

  • Variable names must comply with the following rules:

    • Must begin with an underscore character

    • Must begin in the leftmost byte of the XPUVNAME field

    • Must be padded on the right with blanks if the variable name is shorter than 9 bytes

    • Must not contain embedded blanks

    • Nonblank characters after the underscore must consist of the following alphanumeric or national characters:

      • A through Z,

      • 0 through 9,

      • #, @, $

  • Variable data must comply with the following rules:

    • Must begin in the leftmost byte of the XPUVDATA field

    • Must be padded on the right with blanks if the variable data is shorter than 8 bytes

    • Must not contain embedded blanks

    • Nonblank characters must consist of the following characters:

      • A through Z,

      • 0 through 9,

      • #, @, $, -, .
