hi there,
i ran the comparison 4 times.
each time runs a pair of jobs.
job 1 has the poster original evaluate.
job 2 has the avaluate you suggested.
1st comparison:
original:
| Code: |
-----TIMINGS (MINS.)------ -----PAGING COUNTS----
TCB SRB CLOCK SERV WORKLOAD PAGE SWAP VIO SWAPS
.87 .00 2.0 435 BATCH 0 0 0 0
0000 - TIME=09.42.56
TOTAL TCB CPU TIME= .87 TOTAL ELAPSED TIME= 2.0

2nd comparison:

the result is the same, except for comparison 3. it may be due to the machine load situation at the moment of the execution.
each evaluate is tested 900 million times and the jobs ran at the same time to ensure they were under the same conditions.
the program:
| Code: |
> APPLID(ROS0P03) USER(HB1,E817252)
> LIB(HB1.EVTPTST0) SCRL CSR COLS 00001 00072 LINE 000062
> <...+....1....+....2....+....3....+....4....+....5....+....6....+....7..
000062 000790 PROCEDURE DIVISION USING LK-PARM.
000063 DISPLAY 'PARM=' LK-PARM
000064
000065 PERFORM AAA LK-TIMES TIMES.
000066
000067 MOVE 'X' TO A
000068 PERFORM AAA LK-TIMES TIMES.
000069
000070 MOVE ' ' TO A
000071 MOVE 'X' TO B
000072 PERFORM AAA LK-TIMES TIMES.
000073
000074 STOP RUN.
000075
000076
000077
000078 AAA.
000079 IF LK-OPC = 1
000080 EVALUATE TRUE ALSO TRUE ALSO TRUE
000081 WHEN A= SPACE ALSO B = SPACE ALSO C = SPACE
000082 MOVE 1 TO W-RESULT
000083 WHEN A NOT = SPACE ALSO B = SPACE ALSO C = SPACE
000084 MOVE 2 TO W-RESULT
000085 WHEN A = SPACE ALSO B NOT = SPACE ALSO C = SPACE

000088 ELSE

000101 ******* EVALUATE TRUE

Thanks jctgf for your effort,
I think the only conclusion for this is: What form of evaluate statement you use is not significant to processing time and resources. |
