• Microsoft Fortran PowerStation for Windows 95 and Windows NT, version 4.0

SYMPTOMS

Attempting an arithmetic calculation involving a binary and unary operator consecutively fails with the following compiler syntax error:

error FOR3852: syntax error detected between * and -

RESOLUTION

If you use consecutive binary and unary operators in your arithmetic calculations, enclose the unary operation in parentheses.

-or-

Specify the unary operation before the binary operation.

STATUS

This behavior is by design.

! Compile options needed: none

      j = 3
      k = 2
! The following line causes the FOR3852 error
      i = j * -k    ! comment this line for workaround #1
!      i = j * (-k) ! uncomment this line for workaround #1
      print *, i
      i = -k * j    ! use alternate arithmetic form - workaround #2
      print *, i
      end
