MGR.DVL:SETVAR ISITSO "FALSE"
MGR.DVL:SHOWVAR ISITSO
ISITSO = FALSE
MGR.DVL:IF ISITSO THEN
                  ^
A non-Boolean expression was found. (CIERR 9940)

So setting ISITSO to "TRUE" changes it's type to string.

The best solution I've found so far is:

:setvar isitso 1=2
:showvar isitso
ISITSO = FALSE

but...

:setvar true false
:setvar isitso ![1=2]
:showvar isitso
ISITSO = TRUE

I'm still looking for a more direct approach.

Tried using combinations of setvar true {logical operator like xor}
bound(true)

but could not get anything to work consistently to yield a Boolean false
value.
