THEN
IF a#$ = < <= > >= <> b#$ THEN ...
The THEN command specifies a single command to be executed if the condition to its left evaluates to TRUE. For multiple commands to be executed, ommit the THEN and use a code block followed by an ENDIF statement.
Example:
a=5; b=3
IF a < b
PRINT "a < b", 100, 100
ELSE
PRINT "a < b is FALSE", 100, 100
ENDIF
IF a<>b THEN PRINT "a is not b", 100, 150
