/FPP
Invoke the preprocessor on all input files (this is required in order to use
CIF/CELSE/CENDIF when /SPARAM and /VPARAM are not used). This option is implied
by /CLR.
Silverfrost FTN95 Preprocessing
/SPARAM <integer>
Sets the value of all SPECIAL PARAMETERs.
/VPARAM <name> <integer>
Like /SPARAM but allows the user to define a SPECIAL PARAMETER by name, instead
of having all the same value (over-rides SPARAM).
/DEFINE <name> <integer>
As VPARAM. Values defined by either DEFINE or VPARAM can be used within
the Silverfrost FTN95 Preprocessor or the C-style preprocessor.
/CFPP
Invoke the C-style preprocessor on all input files. Use this for #if,
#ifdef, #endif statements.
