Please know that the EZTPXRPT module has a default size of 10 bytes in length. If this is still 10 bytes in length in your cailib from your 6.4 releases from which you are upgrading, then you can be assured that you are not using Extended Reporting and therefore the MOV64PSD JCL member in your CBAAJCL library does not need to be run.
If the length is confirmed to be a number that it is greater than 10 bytes, then you may also do a find on the word 'EXTENDED' in the source of the CA Easytrieve programs in order to determine if this functionality is still being used.
