Hi
Could someone please tell me what is the meaning of * at the end of a mathematical expression in fortran 77. I found the following line where I have an * at the end (3rd line in the code segment) whose meaning is unknown to me-

IF (K .NE. 0) THEN
ROP = RCKWRK(NcI1+I-1) - RCKWRK(NcI2+I-1)
WDOT(K) = WDOT(K) + ROP *
1 DBLE(ICKWRK(IcNU + (I-1)*MXSP + N - 1))
ENDIF

Your reply will be highly appreciated.

RE: * at the end of mathematical expression

The "1" in the 7th column is a continuation character. This was a fortran 77 standard. The whole expression is

WDOT(K) = WDOT(K) + ROP * DBLE(ICKWRK(IcNU + (I-1)*MXSP + N - 1))

Thanks Bill for the clarification. I am not familiar much with 77.
