   It is a history thing.

   A few years ago, on a day when the omission of color in Define
Screens for Linux had me peeved to new heights, I asked Ken "Why
the F%^&* not?". After 20 minutes of questions, I discovered
that Ken did not add color to *nix dscreen long, long ago because
*nix terminals did not have the function keys that DOS/Windows had.
As you recall, under DOS/Windows, you have to select the colors by
pressing SHFT-F4, CTRL-F1, ALT-F8, etc.

   Bottom line: It was an interface issue.

   With that in mind, I wrote some filePro code which allowed
users to select colors from a screen of colored blocks.

       xx    xx   xx   xx  xx  xx  xx
       xx   [xx]  xx   xx  xx  xx  xx
       xx    xx   xx   xx  xx  xx  xx
(etc.)

   It became the basis for fP Color Editor (also in Toolkit #1).
Extending it, I wrote code to read in filePro color settings
(TEXTNORMAL, TEXTINVERSE, POPUPNORMAL, POPUPINVERSE, etc.) and
allow a user to easily change these values. I took a copy of the
"select colors" code and wrote code to read in a screen
and display it. A bit more code to edit the attribute
portion of the screen file and I had a utility which lets
me add color to any existing screen in a snap.

   That is basically what it does. My fP Screen Painter allows
you to easily choose foreground and background colors (pick
and choose from the displayed colors -- every combination is
possible) and then select areas of an existing screen to
apply the color.

   Since filePro screens have a checksum and fP Technologies
has not made public the checksum algorithm, I was not
able to allow users to create new color screens or to edit
the text/fields on existing screens. The color attributes
of a screen do not impact the checksum, so I could have
my utility change that.

   When you purchase the toolkit, you also get the source code
for all 3 utilities, so if you want to change something (fix
a bug or add a feature), you can, even if Bob and I have
ended up in the big bit bucket in the sky....
