That doesn't automatically mean exists() doesn't work correctly, it is far
more likely that your logic code is simply not written correctly for what
you want to accomplish.

You want to print a header to the file if it doesn't exist, and then append
contents unconditionally?  That's what I've gathered from the thread so
far.  it's pretty simple:


::declare DidHeader(1,YESNO,g):
:exists("/path/to/some/file") eq "0" and DidHeader ne "Y":gosub prthead:
::gosub prtlins:

...

prthead:'start your printing here:'by doing something that prints the header:
::DidHeader="Y":
::return:
::end:

...

prtlins:'start your data print here:'by doing something that prints the data:
::return:
::end:


(I'm anal about putting in end's to prevent as much accidental fallthrough
as possible.  Saves on debugging later.)
