fpp
fpp is the preprocessor used by the NAG Fortran compiler. It optionally accepts two filenames as arguments: input-file and output-file are, respectively, the input file read and the output file written by the preprocessor. By default standard input and output are used.
When used via nagfor
, either because the input source file type was
automatically recognised as requiring preprocessing (e.g. .ff90
files),
or the -fpp option was used, the macro
__NAG_COMPILER_RELEASE
is automatically defined to be the integer
release number (major*10+minor, e.g. 61
for release 6.1), and the
macro __NAG_COMPILER_BUILD
is automatically defined to be the build
number (for release 6.1 this will have a value greater than 6100
).
