[cam-users] CPP question: Feature? If yes: Which.

[Peter Paul Smolka]

Hi all,

history.f90 contains at various places:

# if ( staggered ...

# else

# endif

That is: Numbersign, blank, cpp-command.

Generally cpp-commands are written as:

#if ( staggered ...

#else

#endif

e.g. without blank.

As this appears with the variable staggered (and not as standard
coding) the question:

Does above coding utilize a potentially hidden feature of the cpp?
e.g. # if ... is something different than #if ...? : ...............

If yes: What is intended: .................

or

Are blanks simply overread:..............

(e.g. it most likely was included as such for testing purposes).

Best regards, Peter
