It was in a method to set the Foundation OK button status.
The other use of Execute Formula I found was something about getting an int var
for the host to talk to the component. But in this case, at least the string
being executed had been created from text and a variable.
// Project Method: Fnd_Host_GetIntegerValue (variable name) --> Longint
// Allows a component to get the value of a host long integer variable.
C_LONGINT($0;Fnd_Host_IntegerValue_t)
C_TEXT($1;$variableName_t)
$variableName_t:=$1
EXECUTE FORMULA("Fnd_Host_IntegerValue_t:="+$variableName_t)
$0:=Fnd
