DOCUMENT:Q61681 22-NOV-1999 [msdos] TITLE :Use of FASTOPEN and BASIC Application Causes "Disk Full" Error PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:4.01,5.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system versions 4.01, 5.0 ------------------------------------------------------------------------------- SUMMARY ======= When FASTOPEN is loaded and the BASIC program listed below is executed, a "Disk full" error occurs. When FASTOPEN is not loaded, this error does not occur. The following BASIC program creates a random file with a size of 64 MB, and then asks for a "START" and an "END" record within the file to write the records between "START" and "END": OPEN "TESTDAT" FOR RANDOM AS #1 LEN = 1024 CLS PRINT "************** Write into TESTDAT 1024 - Byte Records *********" PRINT INPUT "Start writing at record:"; START INPUT "Stop writing at record :"; FINAL FIELD #1, 1024 AS A$ LSET A$ = STRING$(1024, "H") FOR I = START TO FINAL PUT 1, 65539 PUT 1, I LOCATE 10, 10 PRINT I IF INKEY$ = CHR$(27) THEN EXIT FOR NEXT I CLOSE END Microsoft has confirmed this to be a problem in MS-DOS versions 4.01 and 5.0. We are researching this problem and will post new information here as it becomes available.
