If I have this correct, I think the difference between
standard SIMH
.TAP format and E11 format is that E11 format does not pad blocks to
an even boundary in the file, while the SIMH format does, however in
both formats the block length in the block header in the file reflects
the original block length.
So if I understand correctly--and from this:
http://simh.trailing-edge.com/docs/simh_magtape.pdf
A block byte count is always a 32-bit little-endian quantity that occurs
on an even byte address boundary (i.e. aligned to 16 bits). The block
byte count itself always represents the actual byte count of the block
read and not the padded length of the block.
Do I have this right?
