The ASCII value to be used by SCRIBE as the delimiter when prompting for
input. Note that this is normally set to the following values

|Key|Null|
|SV prompt|CHAR(253)|
|MV prompt|CHAR(253)|
|Ctrl-E'd SV/MV prompt|CHAR(252)|
|Text prompt|CHAR(251)|

The existence of a value in WC_DELIM% indicates to the system that Ctrl-E
(to drop the delimiter a level) is possible. Thus Ctrl-E on a normal prompt
drops DELIM to CHAR(252). Ctrl-E again drops WC_DELIM% to CHAR(251). To
indicate that Ctrl-E is not permitted in a prompt, set WC_DELIM% to null. If
the user then presses Ctrl-E the system will respond with a W812 ("Subvalues
are not allowed") message.
