Even numbered pages are always ending pages. If the parameter length is zero, the ending page is the last page of the document. No special values exist for the ending page.

(Only supported by AS/400.)

0031 16 1-60 USERDATA Specifies the installation specific feature for which it has been defined. If you specify two or more values, they must be enclosed by parentheses.

  • X'00' - (NODUPLEX) Specifies standard simplex printing; printing will occur on only one side of the physical page.
  • X'01' - (DUPLEX) Specifies that printing is to occur on both sides of the physical page. This permits the print data set to be bound on its side.
  • X'02' - (DUPLEX TUMBLE) Specifies that printing will occur on both sides of the physical page such that the top of the back side is oriented with the bottom of the front side. Tumble duplexing permits the print data set to be bound at the top.

201C 1 1 OPTIMIZE Binary: range X'00'-X'02'
Specifies whether resource (page segments, fonts, etc.) loading is to be optimized to determine the best time to load resources into the printer. This will improve the performance of the loading and printer processes at the cost of more storage and the CPU used during the optimization analysis.
  • X'00' - (NOOPTIMIZE) Indicates that resources are to be loaded into the printer on a page-by-page basis.
  • X'01' - (OPTIMIZE) Specifies that all possible resources are to be loaded prior to the printing of the data set.

(Not supported by MVS, VSE, or AS/400.)

201F 32 2 SHEETS Binary: range 1-32767

This option overrides a FORMDEF specification and will cause only the sheets specified to be printed. A sheet represents the physical page, not the logical page. The numbering begins with the first sheet (sheet 1) and may or may not have a relationship with the page number printed on the pages. The sheet numbers are specified in begin/end pairs. Each number and each range must be listed in ascending order from left to right.

  • X'00' - (BLOCK) Specifies that the printer will block (not report) print-positioning and invalid-character errors.
  • X'80' - (UNBLOCK) Specifies that the printer will not block (will report) both print- positioning and invalid-character errors.

  3. Alphameric characters are A-Z, a-z, and 0-9.
