M99 -- End of Subprogram issue

On the end of my toolpath subs I give a block number return callout

O4022
 (NO.4 CENTER DRILL)
N0220 G00 G90 X-2.951 Y5. (B0.) G54P[#900]
N0230 G43 H17 Z.75 S10000 M[#933]
N0240 G98 G82 Z.0381 R.35 P6 F60.
N0250 X-5.549
N0260 X-4.25 Y2.75
N0270 G80
N0280 G00 Z4.43
N0290 M99P#192  <<<<<<<<<<<<<< M99 return to block callout

The sub returns to block N413 in this example

N412 WHILE[#534EQ1]DO1 (SURFACE 2)
IF[#172EQ5301]GOTO501
IF[#172EQ5303]GOTO413
IF[#172EQ5304]GOTO413
#900=[#539+[4-1]]
#192=413<<<<<<<<<<<<<<<<<<<<<<<< defining variable
G91 G00 X0 G54P[#900]
G90 G00 B0.
GOTO602
END1
N413 WHILE[#531EQ1]DO1 (SURFACE 3)<<<<<<<<<<<< program returns to sub
IF[#172EQ5301]GOTO501
IF[#172EQ5302]GOTO501
IF[#172EQ5305]GOTO501
#900=[#539+[1-1]]
#192=501
.
.
.
END1
GOTO501
N601 M98P[#170+1]
N602 M98P[#170+2]<<<<<<<<<<<<<<<<program leaves sub/ Vericut returns here
N603 M98P[#170+3]
N501
M99

Vericut returns to this sub right from where it left. What do I need to add to my M99 Word/Address to tell Vericut to return to the sub block number?

Re: M99 -- End of Subprogram issue

Tim,

Not sure if you still need this.
Right or wrong how I do it is...

In the registers, Set

    WORD_VALUE "P" {
        COND_AND "M" "99" {
            VARIABLE "6000"
        }
    }

In the M_misc, set

    WORD_VALUE "M" "99" {
        COND_AND "P" {
            MACRO "EndSub"
            MACRO "GotoJumpForwardBackwardStart" {
                OVERRIDE_EXP "#6000"
            }
        }
        MACRO "EndSub"
    }

Hope this helps
Clayton
