Hi Mark,
Here's a graphic explanation of what I'm trying to do here...
http://www.clubtype.co.uk/revDev-abc/abc-rev.jpg
I'm miles away from dealing with a list of replacement characters yet,
but in the meantime, I just need to get started on the proper method
of detecting:
Where the cursor is when its clicked in the text field?
Because it may be at the line beginning or in the middle of a word.
The function 'selectedChunk' returns the position of the entered
character in the form of...
char 1 to 0 of field 1 (the first character in the field)
char 1 to 2 of field 1 (the second character in the field)
etc, etc.
So from that, how does Jacqueline get a simple plus or minus value...?
I quote...
Look up the "selectedChunk" term in the dictionary. This gives you the
position of the insertion point, or the position of any selected text,
in the format:
char x to y of field "whatever"
If x is smaller than y, a range of characters is selected. If x is
larger than y, the insertion point is blinking between two characters.
Your script should check to see whether x is smaller than y. If so,
you've got a selection that spans characters, and x-1 would be the
previous character, and y+1 would be the next one. If x is larger than
y, the insertion point is between characters and x+1 would be the next
character and y-1 would be the previous one.
Thanks for any clarity.
Adrian

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?
