Hi All, Thanks to the people who responded to my question about RELEASE'ing a file programmatically. Someone (I lost the message, shame on me, but I remember it well) said that a command executed through system() is executed by the parent CI of the calling program. I have not been able to verify this, but if it's true then MPE is being real clever about it. Anyway it was pointed out to me that AIFFILEGGET can do this, which I had not noticed. Thanks for the tip. -- :) Chris Breemer [log in to unmask]
