Input Comparison Instructions =, <>, <, <=, >,

>= --- 300 to 328

Input comparison instructions compare two values

(constants and/or the contents of specified words)

and create an ON execution condition when the

comparison condition is true.

Input comparison instructions are available to

compare signed or unsigned data of one-word or

double length data.
