I decided to start with a simple function,
before getting involved with what to do with the return value....

Jacqueline covered it much better than me there. The lookupchar
function was indeed intended as a separate function for you to write.
eg. you might do something like this
-- field "input" contains list of chars which should be replaced, eg
"ABC"
-- field "output" contains your desired output chars in matching
order, eg "123"
function lookupchar tchar
get offset (tchar,field "input")
if it = 0 then return tchar else \
return char it of field "Output"
end lookupchar
So... I made a new main Stack: lookup.rev,
created three fields: editedText, input, output,
and a button to run the script.
ABC is first line of 'input' field.
123 is first line of output filed.
in field editedText, ABC is entered.
Button is pressed.
Result: "Error in handler"
Hint: function.
This function should work in its own right - yes?
