Addressing Rules and Examples

Chapter 4

418

If the accumulated value of counter 1 is greater than or equal to the

accumulated value of counter 2, then the number 1 is stored in word 23 of

input file 12. If the accumulated value of counter is less than the

accumulated value of counter 2, a value of 0 (zero) is stored in word 23 of

input file 12.

Resulting Values

The result of an expression is a 32–bit value. If the high–order bits are

not significant (that is, if they can be truncated without changing the value

of the expression), then the result can be stored in a data field that is less

than 32 bits long. Attempting to put a value into a field that is too small

for it results in an error code of 215 (Appendix B).
