#ELSE ( -- ) [FTH] => "FORTH"
The implementation of #ELSE is done in C for speed and
being less error prone. Better use the ANSI-compatible
[IF] [ELSE] [THEN] construct.
#ENDIF ( -- ) [FTH] => "FORTH"
end of #IF #IFDEF #IFNOTDEF and #ELSE contructs
(a dummy word that does actually nothing, but #ELSE may look for it)
#IF ( -- C: state-save-flag mfth-if-magic S: ) [FTH] => "FORTH"
prepares for a following #IS_TRUE or #IS_FALSE,
does basically switch off compile-mode for the enclosed
code.
better use the ANSI style [IF] [ELSE] [THEN] construct.
#IFDEF ( "word" -- ) [FTH] => "FORTH"
better use [DEFINED] word [IF] - the word [IF]
is ANSI-conform.
#IFNDEF - no description, sorry
#IFNOTDEF ( "word" -- ) [FTH] => "FORTH"
better use [DEFINED] word [NOT] [IF] - the word [IF]
and [ELSE] are ANSI-conform, while #IFDEF #ELSE are not.
#IS_TRUE ( C: state-save-flag mfth-if-magic S: test-flag -- ) [FTH] => "FORTH"
checks the condition on the CS-STACK.
Pairs with #IF
better use the ANSI style [IF] [ELSE] [THEN] construct.
#IS_FALSE ( C: state-save-flag mfth-if-magic S: test-flag -- ) [FTH] => "FORTH"
checks the condition on the CS-STACK.
Pairs with #IF
better use the ANSI style [IF] [ELSE] [THEN] construct.
#DEFINE - no description, sorry
#PRAGMA - no description, sorry
