cmddump1

Usage

Overview

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
