TXT2COM (Keith P. Graham)
- See TXT2COM for other things with that name.
TXT2COM is a DOS utility that converts a text file to a COM file that, when executed, displays the text in a full-screen viewer. It was developed by Keith P. Graham.
To recover the original text file, run the .COM file in a DOS environment, then press the 'T' key.
Later versions include TXT2RES and/or TXT2PAS, special-purpose variants of the software.
Later versions support special features enabled by markup syntax in the source document.

Overview of releases
The version numbering convention approved by the change log is that versions through 2.2 have one digit after the decimal point. Then came versions 2.03 through 2.10, which have two digits after the decimal point.
Some of the information in this table is guessed, as some releases do not contain a clear version number. For clarification, the "Size" column is the size in bytes of the TXT2*.COM file.

Versions 2.04 and 2.09 might also have been released, but they haven't been found.
There's evidence of at least three different "2.06" versions, and three "2.09" versions. Some of them might be registered versions, not freely distributable. Some might be internal versions, used only by the author.
