Intel Fortran macros

[Ben136KBC]

*I am attempting to define a macro iidatac which is defined to be "iidata," (note the comma at the end) or in some cases "" (blank, nothing).

So on the command line I add:

    /define:"iidatac=iidata,"

But then in the code I get this:

..\BlenderUnitOperation\krs_fortran_code\IsCacheableAssay.f90(1): error #5082: Syntax error, found IDENTIFIER 'IASSAYNUMBER' when expecting one of: ) ,
logical function IsCacheableAssay (iidatac iAssayNumber)
--------------------------------------------------^

Why? I expect the line "logical function IsCacheableAssay (iidatac iAssayNumber)" to become "logical function IsCacheableAssay (iidata, iAssayNumber)"

The manual does not contain much explanation of these subtleties...

Please help!

Hmm if a preprocess it with /E, then I see the correct substitution. So why is the compiler complaining then?

I also need to use this macro:

/define:"iidatap=iidata%"

But when I preprocess the file, the % seems to disappear?

I am using:

Ok, it looks like you need /fpp to get it to process the macros.

And for the % to work, you need %%% if it is inside a makefile. I am not a fan of macros, but in some cases they are necessary.
