Page of GC20-1807-7 As Updated April 1, 1981 by TNL GN25-0S29 SEQUENTIAL ACCESS METHOD -- DECLARATIVE MACROS CMS/DOS supports the following declarative macros: I • DTFCD - Types X'02' and X'04' I • DTFCN -Type X'03' i DTFDI - Type X!33! I • DTFMT -Types X'10', X'11', X'12', and X'14' I • DTFPR - Type X'OS' I. DTFSD - Type X'20' The CDMOD, DIMOD, MTMOD, PRMOD, and SDMOD macros generate the logical laCS routines that correspond with the declarative macros. The operands
that CMS/DOS supports for the DTF are also supported for the xxMOD macro. In addition, CMS/DOS supports three internal macros (DTFCP, CPMOD, and DTFSL) that are required by the. COBOL and PL/I compilers. CMS/DOS does not support the ASOCFLE, FUNC, TYPEFILE=CMBND, and OUBLKSZ operands of the DTFCD macro. CMS/DOS ignores the SSELECT operand and any
mode other than MODE=E. Figure 35 describes the DTFCD macro operands and
their support under CMS/DOS. An asterisk (*) in the status column
indicates that eMS/DOS support differs from DOS/VS support.
