SYMPTOMS

The GetCharQQ function does not terminate the program when a CTRL+C or CTRL+BREAK is entered at the keyboard. Instead, the ASCII value for that key sequence is returned (ASCII 03).

STATUS

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

MORE INFORMATION

To reproduce this behavior:

  1. Build the TKEYS.FOR sample program with FORTRAN PowerStation. This file is in F32\SAMPLES\RUNTIME. No compile options are required.
  2. Run TKEYS at the MS-DOS prompt.
  3. Press CTRL+C. The following will be displayed:

    ASCII: yes Char: Decimal: 3 Hex: 0003

  4. Press CTRL+BREAK. The same values will be displayed.
  5. To exit, press:

    q y <space> <space>

FORTRAN PowerStation version 1.0 can be differentiated from the maintenance release version 1.0a by invoking the linker. Typing link32 | more 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.
