/*** iDBCCharRplc - Replaces a character in a string.
*
* written by: John G. Nelson, Pacific Software Publishing Inc.
* copyright: Pacific Software Publishing Inc.
* date: 10/91
* purpose: Allows a single (DBC or sbc) character in a DBC
* string to be replaced by another (DBC or sbc) character.
* The replacement only takes place if there is
* sufficient room in the string.
* parameters: pdbcString : Pointer to DBC string.
* iOffset : Byte position of character to be replaced.
* pdbcChar : Incoming character.
* iMaxLen : Length of pdbcField in bytes.
* return: iOffset : Replacement does not have enough room.
* iNewOffset : Offset indicating position of character
* immediately following newly replaced character.

    Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

    This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

    But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
