VERS9203 contains an invalid tag in the entry of node UTORVM:
 
       :links4.UTORMVSB(P,1M), RYERSON NRCVM01(P,64K) UOTVM(P,64K)
 
The extra  comma after the definition  of the UTORMVSB link  is not valid
and prevents LISTSERV from building its tables. The error message you get
is "Error 100 from LSVBGN". Do not install VERS9203 until you receive the
VERS9204 update, which is being generated as I type these lines.
