AVars and the program compile operation

[Bob Frazee]

Can anyone explain the program compile operation in detail? After making an edit (in this case, activate a DelAVars instruction), I use 'check' which returns no errors found. I will exit the editor, power the calculator down, then up, try to run the App and it won't run. It ends up being a convoluted affair to get it running again. It appears the compile operation does not do a complete compile of the App when the 'check' operation is performed. Any information would be appreciated.
Thanks
