Hi,
If you transfer an XMI file (like RFE is), the receiving file has a record length of 80.
The blksize should be a multiple of 80.
Afterwards you can transfer in binary mode file rev370ld.xmi with IND$FILE to your system.
With PDSLOAD you can copy the file to a partitioned load library.
Copy this library (with RFE 3.3 or RPF 3.3) to SYS2.CMDLIB will complete your installation.
Cheers,
Rob
