No. Not built in that is. I think I have seen some parser
for it some time somewhere. You might as well write your
own, but will be very difficult considering the freedom
you have for declaring variables in qbasic.
Another thing most people do is a fortran, Pascal like solution:
start your program( and even your subprogram) with an explisiet
declaration of all variables and constants you are using. Although
its not necessary in qbasic.

Copied probably the sub/function from another program ?
I have had this problem sometimes with duplicate names
too. I think it has something to do with the way the IDE
handles cut and paste operations.
Anyway: if you be careful to make your subs/functions
before you are pasting anything in its body, then I think
you avoid the error.

Dan, Vernon Buerg has a QuickBasic 'cross reference' utility which would give
you this.  It is shareware.  You should be able to locate it somewhere on the
net, or another QuickBasic cross reference.

Of course!!! Just think how happy you'd be if you got a copy of powerbasic
v3.2 that is about 6 years younger than Qbasic and has JUST hit the market!
:)

There are, probubly, some routines out there to do that but if you'll get into
a more modular style of programming (SUBs and FUNCTIONs) you'll find that you
REALLY don't need to go through all that!

Probably something to do with WinTrash! Try dropping out to a full DOS window
and using Qbasic's editor/IDE instead of clipboard. Sounds like there is a
control character being imbedded in your text.
