Prototype selection

Although you may specify multiple statements with the variable prototype format, only one of these $RCUDSN statements is selected during execution to generate the user data set name.

The TYPE, STKIC, and GDG macro statement parameters determine which of the multiple statements will be used; the first of the statements that matches the conditions specified by its parameters is the statement selected to generate the user data set name.

The TYPE, STKIC, and GDG macro statement parameters are described below:

  • Use the TYPE macro statement parameter to select a prototype based on the type of file being produced. For the Image Copy utility, valid types are IC1 through IC10. If you omit the TYPE parameter, the prototype is selected for all output file types.
  • Use the STKIC macro statement parameter to select a prototype based on stacking or non-stacking of output image copies. Specify STKIC=Y to select the prototype for stacked image copies; specify STKIC=N to select the prototype for non-stacked image copies. Omit the STKIC parameter to select the same prototype for stacked and non-stacked image copies.
  • Use the GDG macro statement parameter to select a prototype based on whether the output image copy is being generated as a GDG. Specify GDG=Y to select the prototype for generation data sets and GDG=N for ordinary data sets. Omit the GDG macro statement parameter to select both types.

Important

The GDG macro statement parameter is not used to determine whether a GDG is to be created; it is used only to select a prototype based on whether the utility is creating a data set as part of a GDG. You control whether the utility creates a generation data set by using ICGDG(Y) on the control statement or options module. The user exit should return only the GDG base name; do not include a generation number specification such as (+1).
