Usage:

mme     gegen
zero    ,ARGLIST
zero    CODE

Where:

ARGLIST

points to an argument list for the call (see below).

CODE

indicates the operation to be performed. The following decimal codes are supported.

Description:

MME GEGEN provides an interface with the Tape Management System (GTMS). The argument list indicated by ARGLIST has the form

zero    STATUS,ARG1
zero    ARG2,ARG3
zero    ARG4,ARG5
zero    ARG6,ARG7

where the ARGn values are pointers to arguments and STATUS is a pointer to

bss    2

MME GEGEN records a status in bits 0-17 of this. Octal 0400000 indicates success; errors are indicated with an octal status of 0400nnn where "nnn" is an octal error code.
