为什么abaqus子程序umat去掉write语句就不能算了？

debug子程序umat的时候发现，此处加了write语句可以算，

CC------------------------------------------------------C

c       WRITE (7,*) 'DDSDDE=1'!!!!加

       DO 100 IN=1,NTENS

        DO 200 JN=1,NTENS

c       WRITE (7,*) 'DDSDDE='!!!!加

         DD_TEM=0.0D0

          DO IS=1,42

          DD_TEM=DD_TEM+A_TEM(IN,IS)*B_TEMNEW(IS,JN)

          ENDDO

         DDSDDE(IN,JN) = DDSDDE(IN,JN)-DD_TEM*DETERINV

200      CONTINUE

100      CONTINUE

c       WRITE (7,*) 'DDSDDE=',DDSDDE

      ENDIF

CC--------------------------------------------------------C      

       RETURN

       END 

      

去掉之后出现错误：
