IDz Code Coverage Enhancement: Number of times a statement was executed

years ago there was a tool that was very similar to RDz Code Coverage. One thing it had that would be good to add to RDz code coverage would be a count of the number of times a statement was executed. This would be helpful in fine tuning if/then/else and evaluate statements.

For example:

Evaluate POLICY-TYPE
WHEN ‘01'
Statements 1
WHEN ‘02'
Statements 3
WHEN ‘03'
Statements 20
WHEN ‘04'
Statements 90
WHEN OTHER
Statements 0
End-evaluate.


Although logically you would code it this way, but based on the counts you may want to change the order to check for 04 first (90), then 03 (20) to be more efficient.

It may only be a few extra lines of code executed but if you multiply these few lines times the millions of policies it is checking it could impact the total run time.

Or something like this:

Evaluate POLICY-TYPE
WHEN ‘01'
Statements 1
WHEN ‘02'
Statements 3
WHEN ‘03'
Statements 20
WHEN ‘04'
Statements 90
WHEN OTHER
Statements 200
End-evaluate.

Based on these counts, you may want to add a SYNCSORT step to the job to filter the input and eliminate all but a few policy type. I used this fix for one job that an input file of several 100,000's records to less than 50,000 and the overall run time by several hours.
