The following should work because TS saves local variable values
in separate contexts for each instance of a function call.

----------------------------------------------------------------------
{function valuewhen
 returns -999999 until the tested condition is true for maxcount number
 of times, after which the passed return value is returned.}

inputs:
    maxcount(NumericSimple),
    testcondition(TrueFalse),
    returnvalue(NumericSimple);

var: counter(0), savedretnval(-999999);

if counter < maxcount then begin
    if testcondition then counter = counter + 1;
    if counter = maxcount then savedretnval = returnvalue;
end;
ValueWhen = savedretnval;
