Name

       cmddump - simulated TRS-80 CMD file loader

Synopsis

       cmddump [-d] [-i n] [-m] [-p entry] [-q] [-s] [-t] [-x] infile [outfile startbyte nbytes]

Description

       cmddump displays information about TRS-80 DOS CMD (binary executable) files.  It takes a
       mandatory input CMD file infile, and an optional triplet of arguments: an output file
       outfile, a starting offset of startbyte into the CMD file infile, and a number of bytes to
       dump, nbytes.  If startbytes is specified, the given byte range is dumped from the
       simulated memory after loading.

       The numeric arguments, including that to the option -i, may be given in any format
       recognized by strtol(3); in other words, traditional C literals for decimal, octal, and
       hexadecimal.

Options

       The optional arguments and their parameters direct cmddump as follows.

       -d     print detailed map; same as -m, but do not coalesce adjacent blocks

       -i n   select ISAM entry n

       -m     print running load map as file is parsed, coalescing adjacent blocks (implies -t);
              default

       -p entry
              select PDS entry entry; cmddump will truncate or right-pad entry with spaces, as
              needed, to the required fixed field width

       -q     quiet; turns off -d, -m, -s, and -t (later flags can override)

       -s     print summary load map after file is parsed

       -t     print text of module headers, PDS headers, patch names, and copyright notices

       -x     ignore anything after the first transfer address
