Yes.

The user should enter % to say treat this expression as a pattern.

eg "%^(#|^)* *" for an identifier (alpha optionally followed by
alphanumerics, with space padding to the end of the field).

On a similar line, does anyone know how to have metacharacters treated
normally when entering a choose parm ?
Eg, we have email addresses keyed, but the find doesn't work, because the
"@" always gets treated specially (PH 710G3, VMS 7.3). I'd thought it was
only special at the end of an expression, but that doesn't seem to be the
case. In fact I don't know what it means in the middle of an expression, but
it finds precious little.
