Shannon,

You can't use VB .NET ?  It would be easier.

Otherwise you might format a string as:

SetPersistDec30 10000000

Then call the KMviaVB WriteLine() to send the String.  I believe you only need to write the persist variable don't you need to read.

More info... It was locked up again this morning.  force closed kmotioncnc and reopened.  still unresponsive.  force closed kmotionserver.exe, opened kmotioncnc everything worked. 

A couple of weeks ago I spent a few unsuccessful hours trying to figure out how to use R/W persist variables with VB6.  Maybe someone has done this and could steer an old programmer in the right direction?

Thanks, Shannon
