GDDM V3R2 Base Application Programming Reference
SC33-0868-02



The Composite Document Print Utility (CDPU) supports printing and viewing of a document, a page segment or an overlay in Advanced Function Presentation Data Stream (AFPDS) format. AFPDS formats supported by the CDPU include LIST3820, LIST38PP, LIST4250, LISTAPA, PSEG38PP, PSEG4250, OVLY38PP, and OVLY4250.

The following restrictions apply to CDPU support of AFPDS documents:

  • The AFPDS document cannot contain multiple documents or page segments. (A document can contain page segments inline.)
  • The structured field length must not exceed 8202 bytes.
  • Input formatted for the 4250 can be viewed but not printed.
  • Secondary input is not supported.
  • Page segments that contain text cannot be printed unless they are imbedded in a document.
    
    
GDDM supports the AFPDS enhancements provided by Print Services Facility (PSF) Version 2.1 on VM and MVS systems. These include support for GOCA graphics orders and IO compressed image.

The formats of individual structured fields, such as "begin-document", are defined in the AFPDS Data Stream Reference, S544-3202.
