cmddump - simulated TRS-80 CMD file loader
cmddump [flags] infile [outfile startbyte nbytes]
cmddump displays information about TRS-80 DOS binary (command) files.
It takes an optional set of flags (described below), an input /cmd
file, and an optional outfile, an optional starting offset of startbyte
into the /cmd file, and an optional nbytes number of bytes to dump.
Non-flag arguments must be given in the order shown. If the optional
arguments are given, the given byte range is dumped from the simulated
memory after loading.
-d print detailed map; same as -m, but don’t coalesce
-i n select ISAM entry n (0x notation OK)
-m print running load map as file is parsed, coalescing adjacent
blocks (implies -t) (default)
-p foo select PDS entry foo (padded to 8 bytes with spaces)
-q quiet; turns off -t, -m, -d, -s (later flags can override)
-s print summary load map after file is parsed
-t print text of module headers, pds headers, patch names, and
-x ignore anything after the first transfer address
