Hello Donald
I'm sure that I'm not the first one to answer this, but in the case
statements, you can use the ascii codes or the rawkey codes, depending on
which you are using in your window. For example, you detect the CR (Carriage
Return) by checking for code 13, if I remember correctly, the ESC character
is code 27. I don't have the chart right here in front of me, but they are
very handy when you are trying to do just such functions.
later,
Laura
