testing for gcode mode

[So not a Guru]

I have a drag knife post I've been working on that needs an odd output. For the knife to lower into cutting position it has to read a G01 on a line by itself.

When I have an arc asthe 1st move of a profile, I still need the "G01" line by itself.

Is there a way I can test what my gcode mode is? This is what my gcode string table looks like:

# Motion G code selection
sg00    : "G00"      #Rapid
sg01    : "G01"      #Linear feed
sg02    : "G02"      #Circular interpolation CW 
sg03    : "G03"      #Circular interpolation CCW 
sg04    : "G04"      #Dwell
sgcode : ""          #Target for string

fstrsel sg00 gcode$ sgcode 5 -1

I think you need to check following variables:

gcode$, cstart$ (as part of the cur_cflg$)

I figured it out.

if prv_gcode=zero, "G"
