.TH "CHKEXE" 1 "2024-05-16" "2.62" "Jindroush's Atari 8-bit tools"
.SH NAME
chkexe \- check and/or disassemble Atari 8-bit executables
.SH SYNOPSIS
.sp
chkexe [\fB\-gaps\fP \fIgap\-size\fP] [\fB\-silent\fP] [\fB\-split\fP] [\fB\-d\fP] \fBxex\-file\fP [\fBoutput\-file\fP]
.SH DESCRIPTION
.sp
\fBchkexe\fP reads an Atari 8\-bit executable (aka XEX file) and prints a
list of segments, each with their start and end address. Run and init
addresses are decoded.
.sp
If no \fBoutput\-file\fP is given, \fBchkexe\fP simply prints the results of
its analysis. With an \fBoutput\-file\fP, a possibly modified copy of the
XEX file is created: Adjacent blocks (e.g. a block ending at $1FFF,
followed by a block beginning at $2000) will be combined. The \fB\-gaps\fP
option can be used to control the threshold for combining blocks.
.SH OPTIONS
.INDENT 0.0
.TP
.B \fB\-gaps\fP \fIgap\-size\fP
Blocks less than \fIgap\-size\fP bytes apart will be combined. Default: \fI0\fP\&.
.TP
.B \fB\-silent\fP
Don\(aqt print informational messages.
.TP
.B \fB\-split\fP
Split multi\-segment executables into one file per segment. The output
files will be called \fIblkNNNN.blk\fP, where \fINNNN\fP is the block number in
hexadecimal. These files are standard Atari executables, with \fI$FFFF\fP
headers.
.TP
.B \fB\-d\fP
Disassemble each block. The disassembler is very simple: single pass,
no attempt to recognize data blocks.
.UNINDENT
.SH EXIT STATUS
.sp
Zero for success, non\-zero for failure.
