IBM Tivoli NetView for z/OS, Version 6.2

Identifying the Command Processor Address

After the command is parsed, you can find the command in the NetView system command table (SCT). You can look up the command using DSICES in one of three ways:

With the parsed command in the PDB
With the unparsed command in the command buffer (CWBBUF)
By command processor module name (the module name is known but the verb name can change, as in a synonym)

The DSICES macro returns the address of the system command table entry. The macro returns the address in an area passed on the DSICES macro as the SCTADDR parameter. This address points to an SCT entry, mapped by the system command entry (SCE), and the address is stored in the PDBCMDA field.

When the DSICES macro returns to the caller, the return code indicates whether the command is immediate, regular, or both. When TVBINXIT is on, the PDBIMMED bit must be set on if the DSICES return code indicates that the command to be called was defined as TYPE=I (immediate) or TYPE=B (both).

You can call regular commands only when TVBINXIT is off and only from task types OST, NNT, and PPT. You can call immediate commands only when TVBINXIT is on and only from task types OST and NNT. Unless otherwise noted in this book, do not call NetView-written TYPE=D commands.
