Thanks Buddy & Karen
I checked RECALC VAR at the online help:
https://www.rbase.com/support/rsyntax/rbgx5/recalc.html
It's been enhanced and is more comprehensive than I recall:
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.
Thanks for the heads-up.

Thanks, Javier
I've long accepted good practice to be:
SET VAR vName DATATYPE = NULL - to create and explicitly datatype a
variable, and ...
SET VAR vName = NULL - to null a variable at the tail end of any
"looping" code segment, anticipating generation of a new value, and
...
CLEAR VAR [ v% | vName_1 ... vName_n ] where there is but a limited
number of variables, local to a routine, before the RETURN, or ...
CLEAR ALL VAR EXCEPT gv% where a large number of variables, local to
a routine, may be safely dispatched; while preserving the state of
"global" variables, which must persist throughout an R:BASE session.
I "kinda" share your recollection re: RECALC VAR. Anyone?
Much appreciation, and warmest (July) regards, Bruce

First and as Karen indicated it is best to declare each variable
separately rather than all variables together. I am not sure if
SET VAR = NULL
Is what you have in your code but the preferred/correct way is:
SET VAR vMy_Variable TYPE = NUL
Where “TYPE” is the type of your variable such as INT and so on
Next,
RECALC VAR
to the best of my recollection, stopped working a while back and now
you have to specify the variable or variables you want recalculated:
RECALC VAR vMy_Variable
It is better coding practice anyway and easier to debug/TRACE since
you can see if the value is being changed. I recall running into this
specific problems but the changes above took care of it.

Karen:
Thank you. You and Buddy are spot-on with RECALC VAR.
I suppose it helps that I NOT type RECALC VARS, which is why the
mystery persisted beyond reason yesterday.
So, uh, I need to tighten my game. Apologies.
As for Forms of any stripe, I'm late to the party. But I like the
idea, certainly in this early experimentation period, of total
flexibility in inputting, until I have half a clue as to what I'm
doing.
Always appreciate your help and experience, Bruce

Bruce: I do something like what you want, but with one difference.
I design "search" forms all the time where there's a bunch of
variable edits. Users type in values and it displays a grid with
results of the search.
I always put a "new search" button on the form that clears all those
variables so the user can type in a new search. All those variable
edit fields are now blank. This is the exact code from the button:
SET VAR vSBLNo INT = NULL, vSPick INT = NULL, vBLWhere TEXT = 'LIMIT
= 0', +
vSTranDate1 DATE = NULL, vSTranDate2 DATE = NULL, vSAcctNo INT =
NULL, +
vCAcctNo INT = NULL
RECALC VAR
I've never had this NOT work.
The difference: don't ask me why, but I have never used a "variable
form". Never. I always bind the form to a table, usually a
"FormDummy" table that has a couple useless rows.

Thank you, Buddy. On closer inspection, after I sent my message, I
TRACED the variable subset as its values were NULLed just before the
SETFOCUS.
The RECALC VAR has no effect on this:
What is in fact happening is that the DISPLAY of those variable
values is not being cleared from their Variable Edit controls during
the rotation.
But when I Tab away from the first control in the Tab Order [a
Variable Radio Group - one of the retained values ], the VE controls
for the NULLed variables go blank, as intended.
So the real question is: How does one blank the display of
now-NULLed previous values within their associated controls?
Much appreciated!

Have you tried RECALC VAR after settling them to null and before
the setfocus

Fairly new to Forms.
A Variable Form provides values to an On Click EEP in a Bit
Button. The EEP succeeds at its tasks, then returns FOCUS to the
first control in the Form's Tab Order, as intended.
One subset of variable values survive the rotation, as intended. A
second subset of variable values must be NULLed during the
rotation, so that their associated controls are blank when the
Form reappears.
I've failed to clear this latter group of values, variably using
CLEAR VAR and SET VAR = NULL commands:
(a) ahead of the SETFOCUS at the tail end of the Bit Button's On
Click EEP;
(b) in the Bit Button's On Exit EEP;
(c) in the On After Start EEP of the form itself.
It's gottta be something basic.
What is the established procedure for clearing a subset of
variable values when rotating directly back into a form from a
prior instance?
