Problem:

Using the following code:

01 XX1.

03 YY1 PIC X.

01 ZZ1 REDEFINES XX1 PIC 9.

The Impact trace with starting point of ZZ1 should be XX1 and YY1, but it's not, what's wrong?

Resolution:

It seems that the options that were set were preventing the expected results.

Changing the options to include children and redefines brought in the expected result set and worked well.
