C   --*** RENELB *** (GJOIN) Renumber connectivity in element blocks
C   --   Written by Amy Gilkey - revised 09/29/87
C   --
C   --RENELB renumbers the nodes in the connectivity arrays.
C   --
C   --Parameters:
C   --   NELBLK - IN - the number of element blocks
C   --   IOFFNP - IN - the nodal offset: if positive, add to node number;
C   --      if negative, use IXNP
C   --   IXNP - IN - the new node number for each node
C   --   NUMELB - IN - the number of elements in each block
C   --   NUMLNK - IN - the number of nodes per element in each block
C   --   LINK - IN - the connectivity for each block
