Indeed and, in general, I speel (!) out all commands in full - it's so much
easier to read and find errors later.
A few exceptions, though: SET VAR for one...

I rest my case - spell it out :)

Wouldn't it have to be VARI rather than VARS? I would have expected just VAR
to work, though.

Doug,
I believe the short form would be RECALC VAR without the ‘S’.

A small side note that I found out the hard way: spell out VARIABLES when
you do a RECALC VARIABLES.
RECALC VARS does not work, as I incorrectly assumed.

Reading in the HELP system for RECALC:
“When you use the RECALC command without any options, RECALC redisplays
only the variable in the field that started the EEP, and recalculates only
expressions using that variable. Use the VARIABLES option to force redisplay of
all variables placed on the form and recalculation of all table expressions.
Use the TABLES option to force recalculation of expressions in the other tables
used in a multi-table form. The TABLES option recalculates lower tables only,
not the current table.”
This leaves me unsure about the solution suggested below. Whether to use
RECALC or RECALC VARIABLES in your case depends on where the code was triggered
– was it triggered by the object you want to redisplay? If so, RECALC should
only refresh that one object. If elsewhere, you may be stuck with the flicker.
What version of R:BASE are you using? Generally speaking, flicker problems
caused by screen redraws were reduced if not eliminated in either later builds
of 7.5 or early 7.6. But I can see where a form with several variable images
could be a problem if every one of them was “refreshed” every time you
recalculated variables.

Have you tried RECALC VARIABLES instead of just RECALC? AFAIK, RECALC
VARIABLES will not cause the entire screen to refresh.
Just on a whim, assign a component ID to one of the images, and try this:
Change the variable behind the image
Do a RECALC VARIABLES
Now do PROPERTY [componentid] REFRESH ‘TRUE’
The idea is to refresh just the one image.

Ok, I guess for the moment, I don't have any options. I asked for the
"Object Specific Recalc" enhancement, but I am a mere user. Do you think it
would be a good idea to request your version of the enhancement, ie a "Redraw =
True or False" Property? My programming is working very well so far except for
all of the objects blinking a lot, so I want to keep going with it. I could
request another enahancement, but I don't want to ask for too much.

The Variable Image Object does NOT change after the EEP changes the value

refresh the appearance of a Variable Image object without using RECALC??

Not to the best of my knowledge. I also use RECALC when I've changed
some variable values (text variables in my case) in code and want the screen to
reflect the updates. This works fine for me but I don't have images — or more
than one or two, anyway.
I think what you want is to request an enhancement like PROPERTY
VariableComponentID REDRAW 'TRUE', which is guaranteed to redraw only a single
component using the current value of the variable attached to it.
