/*
** MKMSG [-h cfile] [-inc afile] [-asm srcfile [-min|-max]] txtfile
**
** take message file and produce assembler source file. lines in txtfile
** can be of 6 types:
** 1) "<<NMSG>>" -- use near segment
** 2) "<<FMSG>>" -- use far segment
** 3) "#anything" -- comment line (ignore)
** 4) "" -- blank line (ignore)
** 5) "handle<tab>number<tab>message_text"
** -- message with number and symbolic handle
** 6) "<tab>number<tab>message_text"
** -- message with number but no symbolic handle
**
** the -h file gets "#define handle number" for those messages with handles.
** the -inc file gets "handle = number" for the same messages. the -asm file
** gets standard segment definitions, then the messages are placed either in
** a near segment (MSG) or a far segment (FAR_MSG) depending on if they follow
** a <<NMSG>> or a <<FMSG>>. if neither is present, <<NMSG>> is assumed. if
** -min or -max is given with -asm, the minimum or maximum amount of 0-padding
** is calculated and placed in the .asm file. any combination of the options
** may be given, and if none are present then the input is only checked for
** syntactic validity. maximum and minimum amount of padding depends on the
** length of the individual messages, and is defined in the cp/dos spec
**
** If the -32 switch is supplied then the -asm file will be compatible
** with a 32 bit flat model operating system. In which case <<NMSG>> and
** <<FMSG>> cause the messages to be placed in two tables. The tables are
** named MSG_tbl and FAR_MSG_tbl respectively. These are within the 32 bit
** small model data segment.
**
** NOTE: This file is no longer used for NT MASM. Instead its output was
** converted to asmmsg.h and asmmsg2.h and slimed. This was the quick and
** dirty way to be able to compile masm for other processors. (Jeff Spencer)
** For more info read the header on asmmsg2.h.
