If both sides are configured correctly, you just enter the following :

NRJE
sub fname;m=132    (or whatever the recordsize is)


The maximum record width is 248 bytes,  which is 265 configured bytes minus
17 overhead bytes.   If your record size is larger,  you will need to write
a simple program to break the file down into smaller records and piece it
back together on the IBM.

If the (m=)  does not work, let me know and I will help you with the HP and
IBM config parameters.
