Since RBase can't talk to the Printer, and the file is simply deposited into a "pickup" directory, how would RBase know when to delete the file (at lease using the methodology that Mike Sinclair is using in the example)?

(Actually that’s a line of caution – but never mind.) _If_ the print fails for _any_ reason the chances are you’ve lost the file and have to re-run the report (or whatever). Regards, Alastair.

Use a Form timer. Use only this code in the Form Timer EEP: SET Var vchkfile = (CHKFILE('c:\main\mike.txt')) IF vchkfile = 1 THEN COPY c:\main\mike.txt \\servername\printername ERASE c:\main\mike.txt ENDIF put the initialization of the variable vChkFile in your onBefore Start EEP: SET Var vchkfile INTEGER Get in the habit of spelling VAR fully. RStyle won't correct it to VAR from just V. I know it's a habit but there might come a time when it is unacceptable and then you would have hoards of V's to find and fix. The form Timer is a low cost gizmo that runs in its own thread (just the same way windows scheduler runs). Set the timer for however many milliseconds you want to check for the file. ----- Original Message ----- From: "Michael J.

Here is my code... LABEL start SET V vchkfile = (CHKFILE('c:\main\mike.txt')) IF vchkfile = 1 THEN COPY c:\main\mike.txt \\servername\printername ERASE c:\main\mike.txt ENDIF GOTO start RETURN Here is my question... Do I want to run the above file as a stand alone file, ie a continous loop OR would I be better off trying to use a TIMER EEP within a form? I assume the form would be better because I should be able to "turn off the code" by closing the form. What I don't uderstand is where I need to put the EEP. Would it be a "On Before Start EEP" or a TIMER EEP (what is the difference?) Does it matter if I start the form with EDIT USING formname vs ENTER USING formname? Does the interval specify how often the EEP runs (ie I don't need the LABEL start and GOTO start loop), or does the interval specify the time between the moment the form is started and the time the EEP fires (in which case I assume I would still need the LABEL start and GOTO start to make the code keep checking the folder for files? I am trying to quit using Rbase for DOS (even though I love it), this will get me one step closer! Any help would be great!
