I rarely want the last block to be padded. I consider this a
practice that conceals failures that should be discovered as
early as possible. I shudder that some IBM VM pages recommend
"... | fblock 80 xx | ..."
A Horrid Example:
http://www.vm.ibm.com/download/
- Click on the package's v,
- Instruct your browser to save the file to disk
- Upload the file to VM in BINARY
- Run the file through this pipeline (where 'fn' is the name
of the file you uploaded):
PIPE < fn VMARC A | fblock 80 00 | > fn VMARC A F 80
... if any padding occurs, it indicates a failure in the
"save" or the "upload" operation. Padding is unlikely to
repair it.
