: conditional test (=,<,>); true commands ; false commands ;
Usage
The conditional test works like the IIF function from visual basic. A good reference on the use of IIF can be found in the wikipedia IIF
: The colon indicates the start of the conditional test
; The first semi-colon is the start of the true SDL
; The second semi-colon is the start of the false SDL
; The third semi-colon ends the false code and is the end of the conditional statement
All four, the colon and three semi-colons must be present to form a valid conditional statement.
Example
To toggle a heading between 90 and -90 degrees based on its current setting:
: a = 90 ; <a=-90> ; < a=90> ;
Test : Is a = 90 ; If true set a = -90 ; If false set a = 90 ;
