Void where prohibited. | > +---------------------------+-----------------------------------------------+ > Included in the Power-4gl toolkit is a function which converts a string with control character representations to a string with actual control characters. For example, if you want the string to contain the three characters 'escape', 'ctrl-M' and a normal 'Q' then you would send "^[^MQ". This format for representing control characters is quite standard and is easy to store in a database table. If you want this function, or more information about the Power-4gl integrated function library (extending Informix-4gl), send word. John H. Frantz frantz@centrum.is --
