The information in this article applies to:

  • Microsoft Programmer's Workbench for MS-DOS, versions 1.0 and 1.1
  • Microsoft Programmer's Workbench for OS/2, versions 1.0 and 1.1

SYMPTOMS

Using the Programmer's WorkBench (PWB) version 1.0 or 1.1, when a region of text is selected and the Print function is invoked, the resulting output contains linefeed characters (0x0A) at the end of each line, rather than a carriage return-linefeed (<CR><LF>) combination (0x0D and 0x0A).

Some printer drivers do not recognize this as a valid end-of-line (EOL) character and do not print correctly.

RESOLUTION

The workaround for this problem is to write a program that translates each 0x0A found in the output file to the bytes 0x0D and 0x0A, or use a printer driver that understands this type of file. In fact, most printers have an escape sequence or DIP switch to enable it to recognize this type of file.

STATUS

Microsoft has confirmed this to be a problem in PWB versions 1.0 and 1.1. We are researching this problem and will post new information here as it becomes available.

MORE INFORMATION

To reproduce this problem, open a file that contains the <CR><LF> combination at the end of each line. Highlight a region of text in the file and from the File menu choose Print. Tab to the second field and type in the following: 

   copy %s test.txt
This will copy the region of selected to the file TEST.TXT. Using a standard hex file viewer, you can see that the end of a line is denoted by a single 0A. If you look at the original file using the hex viewer, it will contain 0A 0D at the end of each line.

Programmer's WorkBench will recognize this type of file (with a single 0A at each end of line) and display it correctly if you try to open it within PWB, but many printer drivers do not understand this type of file.
