Using logical processing

– If the operator is NE, LT, GT, LE, or GE, the system tests

the variable data against only the first value in the TABLE CONSTANT statement.

Performance CRITERIA VALUE affects system performance in relation to the

considerations number of characters per page involved. This is a function of the

with the CRITERIA number of tests performed, the number of character columns in VALUE parameter each test, and the number of lines in which the criteria is

evaluated.

The following actions can help you reduce the impact of CRITERIA VALUE processing on your printer throughput speed when printing your applications:

• Restrict the range of lines tested via the LINENUM parameter. This avoids time spent with unnecessary testing of lines that are not supposed to meet the criteria in any case. For example, in a forms application with an address field at the top and mailing information at the bottom, you might use the LINENUM command to prevent tests on the data associated with the address label and mailing info.

• Restrict the columns tested in the CRITERIA VALUE parameter to the shortest possible length, to avoid testing blank space. However, you should be sure that you are providing for all possible values. For example, you should not limit the column size to space enough for only $999,999 if there is a chance that $1,000,000 might occur on a rare occasion.

• For applications in which either CRITERIA VALUE or

CRITERIA CONSTANT can be used, choose CRITERIA

CONSTANT, because it has less performance impact.

• When coding numeric values into TABLE CONSTANTs, for maximum performance, specify the shortest possible numeric string. Omit superfluous leading zeros, trailing zeros, white space, and “thousands” separators. For example, use ‘50000’ instead of ’050,000.00.’ Because the former expresses the same value as the latter but with only half as many characters, it takes much less time to process.
