DOCUMENT:Q63071 17-DEC-2000 [msdos] TITLE :Only First 8 Characters in a Batch Label Recognized PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:4.01,5.x,6.0,6.2,6.21,6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system versions 4.01, 5.0, 5.0a, 6.0, 6.2, 6.21, 6.22 ------------------------------------------------------------------------------- SUMMARY ======= MS-DOS recognizes only the first eight characters of a batch file label; subsequent characters are ignored. NOTE: This eight-character limitation also applies to the %config% variable passed to the AUTOEXEC.BAT file in MS-DOS versions 6.0 or later when you use multi-boot configurations. For example, the labels LATESTCHANGE and LATESTCHANGES are identical to MS- DOS. The line "GOTO LATESTCHANGE" (without the quotation marks) transfers to the first label in the file that has same first eight characters as LATESTCHANGE. MORE INFORMATION ================ The following examples illustrate this limitation. Example 1 --------- The following example goto latestch : latestchanges echo two : latestch echo three displays the following two three rather than displaying the following: three Example 2 --------- The following example :latestch echo zero :latestchanges echo one goto latestchanges displays the following until CTRL+C is pressed, terminating the batch file: zero one zero one zero one etc. Additional query words: 6.22 4.01 5.00 5.00a 6.00 6.20 multiboot ====================================================================== Keywords : Technology : kbMSDOSSearch kbMSDOS621 kbMSDOS622 kbMSDOS620 kbMSDOS600 kbMSDOS500 kbMSDOS401 kbMSDOS500a Version : MS-DOS:4.01,5.x,6.0,6.2,6.21,6.22 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
