Starting with 2.00? there was a version number buried
in the code,
and the VER command would print some text, and then calculate what
to display for the numbers (major version, period, minor version as a
2 digit decimal number.0 (19h gave .25) But, if 1.25 didn't have
that, then somewhere in
COMMAND.COM, there might be text saying
"MS-DOS 1.25", instead of the later ""MS-DOS ", to be followed
by
calculated values. Did 1.25 have ANSI.SYS and CONFIG.SYS?
For somebody who remembers the detaails of the transition, many of
the text messages in
COMMAND.COM might be recognizable.
My recollection of 1.25 was that it had foreign language (at lead
code-page type support) where 1.1 did not. It lasted longer than it
should have.
