PMAC On-Line Command Specification 247

LIST PC

Function

List Program at Program Counter

Scope

Coordinate-system specific

Syntax

LIST PC[,[{constant}]]

where:

• {constant} is a positive integer representing the number of words in the program to

be listed

Remarks

This command causes PMAC to list the program line(s) that it is (are) about to calculate in

the addressed coordinate system, with the first line preceded by the program number and

each line preceded by the address offset. LIST PC just lists the next line to be calculated.

LIST PC, lists from the next line to be calculated to the end of the program. LIST

PC,{constant} lists the specified address range size starting at the next line to be

calculated. To see the current line of execution, use the LIST PE command.

Because PMAC calculates ahead in a continuous sequence of moves, the LIST PC

(Program Calculation) command will in general return a program line further down in the

program than LIST PE will.

If the coordinate system is not pointing to any motion program, PMAC will return an error

(ERR003 if I6=1 or 3). Initially the pointing must be done with the B{constant}

command.
