Re: [Erppcatoolkit-support] Channel issues?

[Joseph D. <jd...@ma...>]

Hmmm.....

not sure what the problem is.  Looks like there are two things going on, one with the events and one with the channels.  I haven't had a chance to evaluate erplab yet.  Adding support for erplab files was actually next on my list.  Could you send me this .set file so I can test it out?  You can use yousendit.com if it's too large to email.
Also, could you type ver in the command window and send me the resulting text?
I'm planning on adding support for erplab over this weekend so if you could get this to me ASAP, that would be great.

Cheers!

Joe
