Hello,

For example using two programs (one main.cod and one def_cod.cod) i use the folwing definition and i can use the variable Vi_Programa in any of them.

main.cod
VAR
    Vi_Programa : INTEGER EXPORTED FROM def_cod

-----------------------------------------------------------------------------
def_cod.cod
VAR
    Vi_Programa : INTEGER EXPORTED FROM def_cod


I use like this and works all time

 thanks jorger,

i have already tried your mentioned methode, and it works well. thanks very much..

but it is also incovienient, while the GLOBAL doesnt work, because i have 50 Rountine in main.cod to share, use your methode i have to add 50 rows in any other programmes.

I'm wanderring, why the GLOBAL does not work... hnnnn

Hi,

I have a very similar problem working with C5G. There is a main program that includes some counters and one of them needs to be shared with a sub-program. No idea how to define a GLOBAL variable with TP - manuals say that the definition should be var_name GLOBAL, but that doesn't work (incorrect variable name). I have also tried editing the sub-program and selecting Program -> Variables -> Import -> then choosing the main program and the variable I need - but then an error occurs, saying that the variable doesn't exist ( ). What can I do to make it work? The only programming device I can use at the moment is the TP. Is there any other way of editing program code than using IDE?
