Notes

We define a "data key" as any character with an ASCII value greater than or
equal to 32 and less than or equal to 253. We've omitted 254 because we
often use that character for special processing.

Typically used in an exception handler written for use inside Clipper's
TBROWSE or ACHOICE.

This is implemented as a pseudo-function via #define.
