Program "keycode" gives the codes of pressed keys and generates a corresponding
termcap file.

To compile :

  * change file name KEYCODE.4GL from uppercase to lowercase :

      mv KEYCODE.4GL keycode.4gl
or
      NAMELOWER KEYCODE.4GL

  * compilation :
      fgl2p -o keycode.42r keycode.4gl

To use :

IMPORTANT: this program is to be used only in ASCII mode ( with FGLGUI=0 ).

The main menu contains two commands :

* "Key" : 
          Gives the definition of the pressed key as returned by function 
          fgl_getkey if it exists else gives the sequence of the key.
          Pressing the key "tabulation" two times exits this command.

* "Termcap" :
          Creates a termcap file with chooosen key definitions or all keys used
          by INFORMIX.
          The generated file is called "keys.tcap" and is create in the current
          directory.
          There are two menu points for this :

    * "All Keys" :
              It asks to press all keys normaly used by a 4gl program and 
              two times the "tabulation" key to validate the last pressed key.
      
          ex: If the word "left" appears, then the program waits for
              left arrow key to be pressed and validated by two 
              "tabulation" keys.
              If left arrow key is defined, then it will generate in the
              file "keys.tcap" :
                                   kl=<exist>:
              else it gives the sequence ( in most cases beginning withe the
              escape sequence in this case "\E" ) :
                                   kl=\E[[D:

              Pressing two times the letter "q" exits this menu point.
              To retry the last key (for example, if the bad key was pressed)
              press two times key "=".


    * "Named variable" :
              It asks first for the name of the termcap variable and then
              waits for the wanted key to be pressed and validated by pressing
              two times the key "tabulation".
              The key "Return" is to exit this menu point.
              The result is the same as the menu point "All Keys".
