2 queries about referred page numbers - eg See D/64 - both only partly covered by TKB 6(q) :- 1. Is there an up-to-date list of formats acceptable to the database - D64, D'64, D,64, D/64, etc. ? 2. Weve had a couple of situations when we needed to insert a theory,ref line referring to alternate mothers names in addition to the #COMMENT(2) line. Which is correct :- #THEORY,REF,(2) SEE D/64 or #THEORY,REF(2), SEE D/64 Thanks, Ted Southcombe
