A File Size Adjustment Request by an Old MS-DOS-Based Program May Not Be Honored (291105)
The information in this article applies to:
- Microsoft Windows 2000 Server
- Microsoft Windows 2000 Advanced Server
- Microsoft Windows 2000 Professional
This article was previously published under Q291105 SYMPTOMS
A file size adjustment request by an old MS-DOS-based program may not be honored. This problem only occurs in "int 21h function 28h" (random block write to FCB file) when CX is set to 0.
CAUSE
This problem occurs because "int 21h function 28h" (random block write to FCB file) is used to write data to a file on the disk, and CX holds the number of records to write. If CX is set to 0, no data is written; instead, the file size is adjusted to be the same as the file position that the random record and record size fields of the file control block (FCB) specify. Windows Virtual DOS Machine (NTVDM) does not adjust the file size for this request.
