In the following code, DSNAME is a character variable of length 8.

Code:
    subroutine get_mask(dsname,is_lin,seq_no)
       character(len=8), intent(in) :: dsname
       logical, intent(out) :: is_lin(9)
       integer, intent(out) :: seq_no
!
       if(dsname(1:7).eq.'Misra1a')then
            is_lin(1:2)=[ .true., .false. ]
            seq_no=1
       else if(dsname(1:7).eq.'Chwirut')then
            is_lin(1:3)= [ .false., .false.,.false. ]
            seq_no=2
       else if(dsname.eq.'Eckerle4')then
            is_lin(1:6)= [ .true., .false., .true., .false., .true., .false. ]
            seq_no=3
       else
          write(*,*)' Unknown data set name ',dsname
          stop
       endif
       return
    end subroutine


The 8.61 version of the compiler does not give any warnings for this code, but the 8.83 version (with or without /64) says:
Code:

[FTN95/x64 Ver. 8.83.0 Copyright (c) Silverfrost Ltd 1993-2021]
0006)        if(dsname(1:7).eq.'Misra1a')then
WARNING - Procedure expected for argument DSNAME.
0009)        else if(dsname(1:7).eq.'Chwirut')then
WARNING - Procedure expected for argument DSNAME.
    NO ERRORS, 2 WARNINGS  [<GET_MASK> FTN95 v8.83.0]

Thanks for the feedback. This regression has already been fixed for the next release of FTN95.
