APPLIES TO

- Microsoft Fortran PowerStation 1.0a for MS-DOS
This article was previously published under Q106723
SYMPTOMS
PowerStation applications spawned with either SYSTEMQQ or RUNQQ hang when input is redirected from a file. Also, the input is split and directed at both the application and the console.
CAUSE
The MS-DOS extender that comes with PowerStation does not handle console input the same way as MS-DOS does. The hang occurs because the spawned application is waiting for an end-of-file (EOF).
STATUS
Microsoft has confirmed this to be a problem in FORTRAN PowerStation version 1.0 and version 1.0a for MS-DOS.
This is not a problem in FORTRAN PowerStation 32.
MORE INFORMATION
Applications that are not MS-DOS extended handle redirection input incorrectly when spawned with RUNQQ or SYSTEMQQ.
To demonstrate the problem, follow these steps:
- Copy both sample programs into the same directory.
- Compile both TEST.FOR and B.FOR with FORTRAN PowerStation 1.0 for MS-DOS.
- Run TEST.EXE.
Sample Code #1 (TEST.FOR)
C No compiler options required
include 'flib.fi'
include 'flib.fd'
if(.not.SystemQQ('b < test.for')) print*, 'systemqq failed'
end
Sample Code #2 (B.FOR)
C No compiler options required
character*20 c
ierr = 0
do while(ierr.ne.-1)
read(*,"(a)",iostat=ierr) c
print*, c
end do
end
