Re: A83: length_program?




The 83p file format has a word-long program length field at 46h-47h bytes
into the file.  You can find this by (at a command prompt) typing "debug
filename" and typing "d 146 147" at the hyphen prompt.  Open the windows
calculator, put it in scientific mode and in hex mode, type in the two
bytes (reversed) and change it to decimal.  This is the length of your
program.  BTW, you can quit debug with a "q" at the hyphen prompt.
