Hi,

I am trying extern keyword to access from one mod file (b.mod) to one variable (var) declared as ASSIGNED block in the other mod file (a.mod). First I added VERBATIM block including extern satement to b.mod as below;

VERBATIM
extern double var_a;
ENDVERBATIM

What I am confused about is then how to use var_a in b.mod. The usage of var_a as a global variable in b.mod has made compilation error. Can anyone give some advice on how to use the keyword extern in mod file?

Thanks so much.

First of all, this is not the way to specify that a variable that is declared in one mod file is to be linked to a variable in a different mod file. Second, even if it was, this may not be the way to accomplish your objective.

So please take a step back and explain what is your objective. If this is in any way proprietary, feel free to email the information to me
