.SH Description
.B cmddump
displays information about TRS-80 DOS CMD (binary executable) files.
It takes a mandatory input CMD file
.IR infile,
and an optional triplet of arguments: an output file
.IR outfile ,
a starting offset of
.I startbyte
into the CMD file
.IR infile ,
and a number of bytes to dump,
.IR nbytes .
If
.I startbytes
is specified, the given byte range is dumped from the simulated memory after
loading.
.PP
The numeric arguments, including that to the option
.BR \-i ,
may be given in any format recognized by
.BR strtol (3);
in other words, traditional C literals for decimal, octal, and hexadecimal.
.SH Options
The optional arguments and their parameters direct
.B cmddump
as follows.
.TP
.B \-d
print detailed map; same as
.BR \-m ,
but do not coalesce adjacent blocks
.TP
.BI "\-i " n
.RI "select ISAM entry " n
.TP
.B \-m
print running load map as file is parsed, coalescing adjacent blocks (implies
.BR \-t );
default
.TP
.BI "\-p " entry
select PDS entry
.IR entry ;
.B cmddump
will truncate or right-pad
.I entry
with spaces, as needed, to the required fixed field width
.TP
.B \-q
quiet; turns off
.BR \-d ,
.BR \-m ,
.BR \-s ,
and
.B \-t
(later flags can override)
.TP
.B \-s
print summary load map after file is parsed
.TP
.B \-t
