Julian, You can do this using SKILL on the command line inside of Allegro as follows: To turn Online DRC off: skill axlDBControl('drcEnable, nil) Note: "t" will be echoed on the command line when the command is successful. To turn Online DRC on: skill axlDBControl('drcEnable, t) Note: "nil" will be echoed on the command line when the command is successful. You could alias out these commands to a function key so DRC can be easily turned on and off. Example: alias F11 "skill axlDBControl('drcEnable, t)" Hope this helps, Michael Catrambone UTStarcom, Inc. ________________________________ From: icu-pcb-forum-bounce@xxxxxxxxxxxxx [mailto:icu-pcb-forum-bounce@xxxxxxxxxxxxx] On Behalf Of Julian Ungureanu (jungurea) Sent: Wednesday, October 31, 2007 6:29 PM To: icu-pcb-forum@xxxxxxxxxxxxx Subject: [PCB_FORUM] DRC check on/off Is it possible to turn ON /OFF DRC check from the command prompt?
