Sorry, should have read over that before sending, meant to say "if exit 
was clicked"...

I'm calling it from a batch file, snippet:
   =================================
1|"%WINGISBASE%\etc\gis_set.tcl"
2|
3|rem if return ok, gis.m start:
4|if %errorlevel% == 1 exit /b
5|
6|"%WINGISBASE%\etc\gm\gm.tcl"
7|
8|"%WINGISBASE%\etc\clean_temp" > NUL:
   ==================================

so line 4 should detect if Exit was clicked and exit the batch file 
straight away, thus not starting gis.m. I can't see how Init.sh handles 
this. gis_set.tcl has
    puts stdout "exit"
but not sure how to detect that. I guess I'll eventually work it out 
though!
