MMOS/2 IO procedure and Codec maintenance utility

Release: 0.1 (experimental)

This utility allows you to view and modify the MMPMMMIO.INI entries. I wrote it, because I had some trouble with redundant IOprocs for the same file types.

The format of the mmpmtool file is ASCII with the following rules:

Each entry in MMPMMMIO.INI is a record. Records muts be separated by empty lines. They must not even contain white space characters.
The First Line of each record is the record type. This mut be either $IOproc or $Codec.
This keyword may pe preceeded by install or remove causing the following Codec or IO procedure to be installed or removed respectively. Any record without one of these keywords is ignored.
Each record consists of items. The Syntax is:
itemname: value
Keywords and item names are case insensitive.
String values must not have quotion marks.
Integer values must follow the C language rules. Hexadecimal number must begin with 0x. Octal numbers muts begin with 0. Omit any leading zeros from decimal numbers, they are taken as octals otherwise.
