This procedure queries the contents of the procedural database. It

is supplied with seven arguments matching procedures on { name,

blurb, help, author, copyright, date, procedure type}. This is

|
accomplished using regular expression matching. For instance, to

find all procedures with \"jpeg\" listed in the blurb, all seven
|
|
arguments can be supplied as \".*\", except for the second, which

can be supplied as \".*jpeg.*\". There are two return arguments for

this procedure. The first is the number of procedures matching the

query. The second is a concatenated list of procedure names

corresponding to those matching the query. If no matching entries

are found, then the returned string is NULL and the number of
