Use #if not defined with OR boolean logic in preprocessor directives

Applications Programming

I am currently using Linux CentOS and programming in FORTRAN 90 using Portland 7.1 compiler.

I am able to set in the preprocessor directives a flag called TEST. when I go to use logic in my code i can write

#ifdef TEST
   execute something
#endif

Furthermore, if I want to negate the logic I can type:

#ifndef
   execute something
#endif

Now, if I want to add some boolean logic like AND, OR etc. I have to use slightly different syntax as follows:

#if defined TEST || defined NEWTEST
   execute something
#endif

This allows me to say if the Flag "TEST" or the flag "NEWTEST" is defined then do something. What I cannot seem to find is how to negate the logic such that it says: if the Flag "TEST" is NOT defined OR the flag NEWTEST is NOT defined...

The syntax I have tried to come up with does not appear to work. I am looking for something similar to the following:

#if not defined TEST && not defined NEWTEST
   execute something
#endif

Any ideas??

Try ! for a negation.

Go for multi-line statement
