INEQUALITY OPERATORS
NOT
N760 WHILE (#135 != #137) DO 10
N770 ------------
-- --
-- --
N790 END 10
The exclamation mark (!) symbolizes NOT. Therefore, Block N760
instructs the 3500i to continue the loop to N790 while the contents of
variables #135 and #137 are not equal (condition true). When the
contents of the variables become equal the expression is false and the
loop terminates.
GREATER THAN
N800 IF (#122 > #134) GOTO 830
N810 ------------
The symbol (>) symbolizes GREATER THAN. Therefore, Block N800
instructs the control to go to (GOTO) or jump to Block N830 if the
contents of variable #122 are greater than the contents of variable
#134 (condition true). If the expression is false, execution continues to
Block N810.
LESS THAN
N840 IF (#123 < #135) GOTO 880
N850 ------------
The symbol (<) symbolizes LESS THAN. The function is the opposite
of GREATER THAN and the expression is true when the contents of
variable #123 are less than the contents of variable #135.
Greater than (>) and less than (<) expressions become
false if the contents of the compared variables are equal.
