SDF macros

The SDF user interface can also be employed for user programs. For this purpose, SDF offers the following macro calls (for a detailed description see the “SDF-A” manual [4]):

CLSCALL CMDALLW CMDANALY CMDCST CMDMEM CMDRC CMDRETC CMDRST CMDSEL	Closes a syntax file hierarchy opened in the program Generates a list of permissible operations Generates EQUATEs for return codes Initiates a semantic error dialog Generates a transfer area for status information Sets a command return code Generates a DSECT for the command return code Reads and analyzes a statement and returns the results Creates a selection menu for defined objects and returns the selection result (both single and multiple selection are possible)
CMDSTA CMDSTRUC	Provides information on active syntax files Generates a standardized transfer area for an analyzed statement in the old format. The transfer area is only evaluated by the RDSTMT, TRSTMT and CORSTMT macro calls that are still compatibly supported (for the new format, see CMDTA).
CMDTA	Generates a standardized transfer area for an analyzed statement in the new format
CMDTST CMDVAL CMDWCC CMDWCO CORSTMT	Analyzes a statement Checks whether a value matches a data type Checks wildcard syntax and compares the patterns Generates a name from a selector, a name and a constructor Initiates a semantic error dialog. The macro call uses the standardized transfer area in the old format and is only supported when compatible. Applications that use the new format of the standardized transfer area must use the CMDCST macro call.
OPNCALL	Opens a separate syntax file hierarchy at program level
RDSTMT	Reads and analyzes a statement and returns the results. The macro call uses the standardized transfer area in the old format and is only supported when compatible. Applications that use the new format of the standardized transfer area must use the CMDRST macro call.
TRCMD	Analyzes a command input and generates from it the desired logging format (see section “Logging”).
TRSTMT	Analyzes a statement. The macro call uses the standardized transfer area in the old format and is only supported when compatible. Applications that use the new format of the standardized transfer area must use the CMDTST macro call.
