Coding, syntax & commands
John,
I tried this in the command window and a PRG:
SET DEVICE TO PRINT
@ 2,46 SAY 'test'
SET PRINT TO
SET DEVICE TO SCREEN
and it sends output to printer as I would expect in both cases. However, if I call this PRG from another PRG or even place this code within a form method, nothing happens when this code fires. I traced it through the debugger, the code is being executed, but no output is sent to the printer. I then issue the above commands in the command window and I get my output correctly. What am I missing here?

You're not going to find a way to do it line by line and that would, indeed create some messy situations if someone else sent something to that printer.

When I run dbase 3 in windows I can issue SET DEVICE TO PRINT and immediately see output directed to the printer line by line with @...SAY (Output is not spooled). Am I forced to spool output with VFP? I guess there's nothing wrong with that, I just assumed I'd see the same output behavior as DBASE.
