I tried the cpytoimpf command you suggested, but the resulting file was not converted to ASCII. I don't see a parm allowing for this conversion. What am I missing?
CPYTOIMPF can be used to flatten a file either to an AS/400 "native" file (i.e ebcdic) or to a flat file in the ifs (i.e ascii).
Here is an example of creating ascii flat file with cpytoimpf:
tostmfcopag(requeested ascii code page)
BTW - you can set the code page of the ifs file if you use PTFs described here.
