Re: [open-cobol-list] Simulating radio buttons.

Hi Again

You could also use the unicode subsection that creates geometric shapes 
for your radio button on/off positions.

They are mostly U25XX

Here is a list:
http://www.fileformat.info/info/unicode/block/geometric_shapes/list.htm

I know we don't have unicode support in the main releases but I bet all 
will be good if enough space is allocated for each unicode character.

Here is a simple program to show the two geometric shapes and validates 
their byte consumption :



>>source format is free
identification division .
program-id. unicode-blocks .
data division .
working-storage section .
01 bulls-eye pic x(3) value is '◎' .
01 circle-with-fill pic x(3) value is '◍' .
01 wait-for-key pic 9 .


procedure division .

display 'bulls-eye ◎ takes ' line 5 column 10 .
display function byte-length ( '◎' ) with no advancing.
display ' bytes' .


display 'circle-with-fill ◍ takes ' line 10 column 10 .
display function byte-length ( '◍' ) with no advancing.
display ' bytes' .
accept wait-for-key .

goback .
end program unicode-blocks .




Just a reminder, to type unicode, it's ctrl shift u and then the code 
such as 25ce
