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.
