Allegro -> Design Workflow - workspace - custom-menu -> system command

Hi,

currently looking at creating new workflow items in custom workspace 

would like to be able to call out windows system variables and or allegro enviroment variables with the "system" command in conjunction

help desc

system
The system command executes the operating-system command you have specified. The system command supports the redirection and wildcard notation of the host operating system.
Syntax
system <OS command>
Example
system mv abc.brd /home/usr/brddir

------------------------------

currently I have to use a .BAT file to do that 

-->

<task name="edit env" command="system 'notepad %HOME%\pcbenv\env'"></task>
<task name="test env .bat" command="system 'C:\tmp\test_env.bat'"></task>

bat file example

notepad %HOME%/pcbenv/env

once I figure it out,  there are many things that could be put in the design workflow - workspace  menu

if you have other wrapper cgywin, etc. please post.

note:  looks like a lot easier to change workspaces - menus ,  then edit custom skill code driven menu system :-)

appreciate any tips/tricks/examples      :-)  Robert
