Intrinsic macros?

[Antoni Gual]

The docs say keywords as HIBYTE are "intrinsic macros". Does this mean they can't be found in header files?
I did a search in the inc folder for HIBYTE and did'nt found it...

[VonGodric]

they are "built in" into compiler as far as i know

You're right! I found them in DATA lines in rtl.bas

Code:

'' name, args, arg[0] to arg[n] names, macro text
imacrodata:
''#define RGB(r,g,b) ((cuint(r) shl 16) or (cuint(g) shl 8) or cuint(b))
data "RGB", 3, "R", "G", "B", "((cuint(#R#) shl 16) or (cuint(#G#) shl 8) or cuint(#B#))"

''#define va_arg(a,t) peek( t, a )
data "VA_ARG", 2, "A", "T", "peek( #T#, #A# )"
''#define va_next(a,t) (a + len( t ))
data "VA_NEXT", 2, "A", "T", "(#A# + len( #T# ))"
