 QB 4.5 - Expression too complex Hi, I have an error in QB 4.5 when I'm trying to compile my program. I never had this error before. The Screen looks like this: -------------------------------------------------------------------------
BC C:\QB\DCF.BAS/O/T/C:512;
[...]
068A 01EA IF Reserve = 1 THEN PRINT "aktiv " ELSE PRINT "inaktiv"
^ Expression too complex
[...]
-------------------------------------------------------------------------
What will I have to do to not get this error anymore? Might changing of the
compiler Options help or will I have to change anything in the Program?
Thanks,
Arne (Germany)

What type is 'Reserve'? If it is a simple datatype, I can't see anything complex here, but is it a function?

Reserve is a Standard Variable, not defined. the Programm contains no DEFxxx instructions - so it's a single, Symbol "!"?

I just tried the expression you were attempting to compile and it compiled just fine for me.

Try compiling the whole program http://people.freenet.de/Elektronikseite/dcf.bas (don't run it - it might hang up if there is no DCF receiver connected!)

Compiles fine with powerbasic, provided the variable "Min" is changed to something else (min is a reserved word). Some BASICs will give the "expression too complex" error
due to a problem it encounters on a prior line. I note
that a line previous to the line in question is inordinately
long. Try breaking it up into a few, smaller lines and see
if your compiler isn't happier.

Just tried it, works fine! Thanks! Where is the limit, 127 Char/line? - Arne

QB 4.5 - Expression too complex I tried it and got the same error using Basic PDS 7.1. I think the error is really 2 lines above where ParDat is assigned. Try something like: ParDat = 0
FOR I = 36 TO 57
ParDat = ParDat + D(I)
NEXT

I'm not sure. My rule of thumb has always been, if it runs more than a few characters beyond the margin, break the line. I also noticed that the line in question forms a sum of
consecutive elements of an array. Did you consider
replacing the explicit sum with a for..next loop?

No! But that is a good idea - i'll think about using for-next loop for the Parity Checksum Calculations. This might make the code much shorter. - Arne

Greg Neill wrote that earlier - you should read the whole thread befor answering! Quote: > Try > something like: > ParDat = 0

I'll think about it. Actually, I have something like this: ParDat = D(36) + [...] + D(45)
ParDat = ParDat + D (46) + [...]+ D (57)
and it works fine.

QB 4.5 - Expression too complex His answer wasn't there when I wrote mine. There's a time lag in receiving newsgroup updates (at least with my ISP). Brad Kunkel www.ibisoftware.com

Sorry, I didn't know that - my provider (T-Online) only needs a few seconds to update the NG, at least with my postings.

Is that all on one line? Try breaking it up like this: IF Reserve = 1 THEN
PRINT "aktiv "
ELSE
PRINT "inaktiv"
ENDIF
And don't forget the ENDIF at the end...
