In response to Nick Sayer's query about the Intel HEX format, the following
information is given in "The Programmer's CP/M Handbook" by Johnson-Laird:-
: 04 0158 00 64 00 01 80 BE
^ ^ ^ ^ (____________) ^
| | | | | |
| | | | | |____ Checksum formed by adding up
| | | | | all of the numbers after the
| | | | | colon and subtracting their
| | | | | sum from 00H.
| | | | |
| | | | |_______________ Data bytes
| | | |
| | | |________________________ Record type, normally 00
| | |
| | |_____________________________ Load address for data bytes
| | on current line.
| |
| |__________________________________ Number of data bytes on line
|
|_______________________________________ Beginning of line marker
I don't know if the record type is ever anything but 00.
