EL _ Strings

[DonC <countach@xxxxxxxxxxxxxxxx>]

Does anyone have an idea of how one would print the value of a
a boolean variable with a FileAppend statement ,i.e., print
TRUE or FALSE ?

I have a boolean input which is used to control the logic, 
and I wish to print its value in the output file (not the
Print Log - it prints OK there using "binput:4" w/o the parens).

Using a FileAppend statement the Power Editor always says 
"String operation expected", no matter what I try (even string 
operations).

Any ideas ?
