re: disable the "-" key

On key label - Do Nothing

Procedure Nothing
Return && Nothing

If you had the job-number (no "-") and a last name (with hyphenated last name) on the same form. You couldn't turn the "-" on for one field and off for another this way.

Wouldn't it be better to trim the "-" out of the data during the LostFocus event?

LostFocus:
this.value = allt(strtr(this.value,"-",""))

Then the user who is watching what they type isn't confused when they press a dead key, but you still pass 'clean' data to your application.
