====int io_flag(..........)====
<big>int io_flag(const char '''*format''', int '''row''', int '''col''', int'''* status''', int '''radio''');</big>
io_flag() allows the user to make a single true/false selection. '''"status" ''' points to the status of the selection, that can be zero or non-zero. If '''"*status" ''' is initially set to anything but zero, io_flag() corrects value to one. '''"format" ''' holds the shape of the checkbox as io_displayflag() function.
io_flag() begins the selection by displaying the checkbox according to its '''“*status”'''. (Remember that the value of '''"*status" ''' is corrected before the editing begins). Then the function waits for the user input.
*If the user input is any of the printable keys (' ' < key <= '~') excluding space, it should be ignored (no action taken). If the user input is any of the function keys, the function is terminated returning the key.
*If the user input is SPACE:
**If '''“radio” ''' is true, then the '''"*status "''' is set to one, checkbox is displayed and function is terminated returning space.**If '''“radio” ''' is false, then the value of '''"*status "''' is toggled between 0 and 1, the checkbox is displayed and function is exited returning space.
