Format of the CVT Macro-Instruction
This macro-instruction defines the symbolic names of all fields in
the communication vector table (CVT). When coding this macro-
instruction, you must precede it with a DSECT statement. The format of
the macro-instruction is as follows:

You specify, in the operand field, the control program that you are
using.
VMS
designates mUltiprogramming with a variable number of tasks.
INT
designates multiprogramming with a fixed number of tasks.
MIN
designates the primary control program.
If the operand field is blank, it is assumed that you are using
multiprogramming with a variable number of tasks.
