Q106721: FIX: Tab Edit Descriptor Can Give Incorrect Results with READ

Article: Q106721
Product(s): Microsoft Fortran Compiler

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft FORTRAN PowerStation for MS-DOS, version 1.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Using the tab edit descriptor (T) in a formatted READ statement can cause data
to read in incorrectly.

STATUS
======

Microsoft has confirmed this to be a problem in FORTRAN PowerStation version 1.0
for MS-DOS. This problem has been resolved with FORTRAN PowerStation maintenance
release version 1.0a for MS-DOS.

FORTRAN PowerStation version 1.0 can be differentiated from the maintenance
release version 1.0a by invoking the linker. Typing "link32 | more" (without the
quotation marks) from \F32\BIN directory will show version 2.8 for FORTRAN
PowerStation version 1.0, and it will show version 1.0f for the maintenance
release version 1.0a.

MORE INFORMATION
================

The sample code below demonstrates this problem. Although the sample uses
internal files, this error also occurs when reading from disk files and the
console.

Sample Code
-----------

  C No compiler options required
        real w,x,y,z
        character*255 wb
  C         12345678901234567890123456789012345678901234567890123456
        wb=' -6704       21       9.3    -399.7    1712.5      .000'
        read(wb,'(T16,F10.3,T26,F10.3,T36,F10.3,T46,F10.3)') w,x,y,z
        print *, w,x,y,z
        Print *, 'Should be:'
        print *, 9.3, -399.7, 1712.5, 0.0
        end

Output:

  9.300000 -399.700000 71712.000000 5.000000

Should be:

  9.300000 -399.700000 1712.500000 0.000000E+00
