You can do a trial run for any source member that you suspect you may have problems converting. You will then get a conversion report for the converted source member that may identify certain conversion errors.
For example, to perform a trial conversion on the source member PAYROLL, type:
CVTRPGSRC FROMFILE(OLDRPG/QRPGSRC)
FROMMBR(PAYROLL)
TOFILE(*NONE)The TOMBR parameter should be specified as *FROMMBR. However, since this is the default, you do not need to specify it unless the default value has been changed. The CVTRPT parameter should be specified as *YES — this is also the default. If it is not, then the conversion will stop immediately.
Using the TOFILE(*NONE) parameter stops the Conversion Aid from generating a converted member, but still allows it to produce a conversion report. For more information on the conversion report, see Analyzing Your Conversion.
