Macro Command Language Processor macros

The Macro Command Language Processor (MCLP) allows (system) commands to be entered without exiting the program mode. The macro CMD is used to invoke the MCLP (with SVC 58₁₆) and to communicate the command name and operands. The MCLP carries out a syntax check before branching to the actual command processing routine itself. After the command has been executed, the program is resumed.

Some of the commands which can be invoked will terminate the calling program (see table 12 (CMD - Call command)). The calling program is also terminated if (user-specific) commands defined using SDF-A and implemented by command procedures are called.

In addition to SDF commands, ISP commands may also be invoked. Input errors in SDF command names may be corrected in interactive mode.

Some of the BS2000 commands contained in the system syntax file of BS2000 cannot be called via the CMD macro, see table 11 (CMD - Call command).

Some of the commands have own macros. The following table compares these macros with the corresponding commands (macros described in the appendix are not included):
