C=======================================================================
C --*** RDSTEP *** (TXTEXO) Read database variables for one time step
C -- Written by Amy Gilkey - revised 03/02/88
C --
C --RDSTEP reads the database history, global, nodal, and element variables
C --for one time step.
C --
C --Parameters:
C -- NTXT - IN - the text file
C -- NVARGL - IN - the number of global variables
C -- NVARNP - IN - the number of nodal variables
C -- NUMNP - IN - the number of nodes
C -- NVAREL - IN - the number of element variables
C -- NELBLK - IN - the number of element blocks
C -- NUMELB - IN - the number of elements per block
C -- ISEVOK - IN - the element block variable truth table;
C -- variable i of block j exists iff ISEVOK(j,i)
C -- TIME - OUT - the time step time
C -- VAR - OUT - the global variables for the time step
C -- * - return statement if error encountered, including end-of-file;
C -- message is printed
C --
C --Database must be positioned in front of time step upon entry;
C --upon exit positioned after time step.
