About
=====

MAWK version 1.3.4-20240622 for DOS.

mawk is an interpreter for the AWK Programming Language. It uses a
bytecode interpreter, and is known for speedy execution.  Both builds
require an 80386 or better and were tested on FreeDOS.

* mawk.exe is built with DJGPP and requires CWSDPMI.EXE

* mawkx.exe is built with OpenWatcom and requires HXRT and 4DOS

MAWK extensions
===============

*   Extended Regular Expressions.
*   Mktime, strftime and systime.
*   New functions: toupper() and tolower().
*   New variables: ENVIRON[] and CONVFMT.
*   ANSI C conversion specifications for printf() and sprintf().
*   New command options: -v var=value, multiple -f options, and
    implementation options as arguments to -W.
*   For DOS, an environment variable MAWKBINMODE and a built-in
    variable  BINMODE. The bits of the BINMODE value tell mawk
    how to modify the RS and ORS variables:

    0  set standard input to binary mode, and if BIT-2 is unset, set
       RS to "\r\n" (CR/LF) rather than "\n" (LF).

    1  set  standard  output  to binary mode, and if BIT-2 is unset,
       set ORS to "\r\n" (CR/LF) rather than "\n" (LF).

    2  suppress the assignment to RS and ORS  of  CR/LF,  making  it
       possible  to  run scripts and generate output compatible with
       Unix line-endings.
