c NOTE: MODIFICATIONS TO *UMAT FOR ABAQUS VERSION 5.3 (14 APR '94)
c
c (1) The list of variables above defining the *UMAT subroutine,
c and the first (standard) block of variables dimensioned below,
c have variable names added compared to earlier ABAQUS versions.
c
c (2) The statement: include 'aba_param.inc' must be added as below.
c
c (3) As of version 5.3, ABAQUS files use double precision only.
c The file aba_param.inc has a line "implicit real*8" and, since
c it is included in the main subroutine, it will define the variables
c there as double precision. But other subroutines still need the
c definition "implicit real*8" since there may be variables that are
c not passed to them through the list or common block.
c
c (4) This is current as of version 5.6 of ABAQUS.
