This article was previously published under Q257404 SYMPTOMS
MS-DOS programs that use command-line arguments may work improperly and may indicate that they are receiving a command line that is missing the first character.
CAUSE
The command-line tail length is at offset 0x80 in the MS-DOS program segment prefix (PSP). Offset 0x81 has a blank in it. The actual content of the tail starts at offset 0x82. Some old MS-DOS compilers, including the Microsoft Fortran for MS-DOS version 5.1 compiler and the Microsoft Pascal compiler, assume that offset 0x81 is the initial character of the command-line tail instead of offset 0x82.
RESOLUTIONTo resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the

WORKAROUND
To work around this problem, change the routine that gets the command-line tail so that it starts with offset 0x81 from the PSP instead of offset 0x82.
STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 3.
