Line 1: Line 1:
 +======Synopsis:​======
 +__input_char__ [-noecho] "<​prompt>"​ {<​stuff>​}
 +
 +======Description:​======
 +This command prompts the user to type ONE character and then runs the 
 +<​stuff>​ and $* will be the user's response.
 +
 +The -noecho option will suppress the outputting of the character to the
 +input line as it is typed.
 +
 +The $'​...'​ expando is a wrapper around __INPUT_CHAR__ in case you were
 +wondering. ​ It's always better to use __INPUT_CHAR__ than $'​...'​ if you
 +can arrange it because it operates asynchronously,​ which means it plays
 +nicely with other commands.
 +
 +======Examples:​======
 +      input_char "Press '​q'​ to quit, any other key to continue: " {
 +         ​unless ( [$0] == [q] ) {
 +            /* do whatever */
 +         }
 +      }
 +
 +======History:​======
 +The __INPUT_CHAR__ command first appeared in EPIC3.003.
