PRODUCT : Paradox NUMBER : 697
VERSION : 3.5
OS : DOS
DATE : August 26, 1991 PAGE : 1/3
TITLE : Recognized keys in PAL WAIT Table, Record or Field
During a WAIT command, PAL script execution pauses for user
input. Most keys pass through to Paradox, but some of them are
blocked by WAIT. This blocking is usually signaled by a beep.
This document is a list of all standard Paradox keystrokes that
are and are *not* blocked automatically by each version of the
WAIT command. For all WAITs, nonstandard Paradox keys (e.g.
<Alt-1>, <Shift-F8>, or <Ctrl-A>) are blocked. WAIT RECORD and
WAIT FIELD are progressively more restrictive than WAIT TABLE;
for each, only the new keys blocked are listed.
In order to use a blocked key, or prevent the use of a non-
blocked key, you must place that key in the UNTIL clause of the
WAIT. Note that some of the non-blocked keys are invalid in the
contexts in which WAIT can be called, so it doesn't really matter
whether they are passed through or not. More information on the
WAIT command is found in the Paradox PAL User's Guide.

NOTE: Any validity checks on the current field *must* be
satisfied before you can leave the WAIT. REQUIREDCHECKS OFF and
ISVALID() can help with this. Also, leaving a WAIT automatically
exits you from fieldview; moreover, many inactive cursor keys in
WAIT RECORD and WAIT FIELD become active in FieldView.
WARNING: The following keys are *not* blocked, and may have
undesired side effects: <Ctrl-F>, <Alt-F5>, <Alt-K>, <Alt-L>,
<Ctrl-O>, <Alt-O>, <Ctrl-Z>, <Alt-Z>
