The SDF macros described in this section cause SDF to request statements.
The macros are stored in the macro library SYSLIB.SDF.<version>, which is supplied with SDF. The macros are described in this manual because they can be used only if a suitable syntax can be defined with SDF-A.
Processing of the macros depends on the SDF version running on the system.
Changes for programs under SDF V4.1A and higher
The layout of the standardized transfer area was changed for SDF V4.1. For this reason the CMDSTRUC macro for generating the transfer area was replaced by the CMDTA macro. In addition, the macros RDSTMT, TRSTMT and CORSTMT for processing statements were replaced by the new macros CMDRST, CMDTST and CMDCST.
The format of the standardized transfer area used up to SDF V4.0 and the macros CMDSTRUC, RDSTMT, TRSTMT and CORSTMT should no longer be used in the new programs; however, for the convenience of the user descriptions can still be found in the appendix (see section “Changes to the SDF program interface”).
standardized transfer area in the old format. The new format can only be used via the Assembler interface!
