# EVW\_NUMERIC

> [HTML Version](evw_numeric.htm)

This switch allows you to also accept "events" consisting of a string of numeric digits followed by <ENTER> .  This is particularly useful when migrating from text-mode (or power-user) environments where users are accustomed to selecting fields or menu options by keying in the corresponding number and hitting <ENTER>.  When you start adding clickable controls to such screens, you may want to replace the "Enter Field #"  prompt with an EVENTWAIT operation, allowing the user the choice of  either clicking on a control (possibly generating an [exitcode](exitcode_aui.htm.md) or a keyboard string simulating what the user could have typed to make that selection), or just typing the desired option # and hitting Enter.

Note that these numeric keyboard "events" are returned to the calling program with _exitcode_ set to 0, and _ctlid_ set to the numeric value entered.  Since the returned _ctlid_ may not have anything to do with a valid control ID, take care not to pass the value back as input to a subsequent EVENTWAIT operation (or else it will probably abort with _exitcode_ 99, meaning invalid control ID.)  In other words, after interpreting the returned _ctlid_, set it back to either 0 or to the ID or a valid control on which you want to place focus for the next EVENTWAIT.

See [EVW\_RAW](evw_raw.htm.md) for a similar option.
