Ooops! Sorry, I'm using a "split" that creates three digit extensions of the form ".[0-9][0-9][0-9]" and had (erroneously) assumed the bin, sbin, etc. files were similarly named <:-) > However there seems to be another underlying assumption: that MS-DOS > expands wildcards in alpha-sorted sequence.

My assumption was that the files would have been ftp'ed in alpha order and, thus, present in the directory in that order! > Another complication: DOS "sort" is little-used, broken, and may > not be in the PATH. \DOS is usually in the PATH and SORT should be therein. How far back (e.g., DOS 1.0?) should we support this? I would imagine 5.0 or 3.3 to be the "oldest" we'd need to support (??) I'll try to dig up earlier versions to verify. Another hack would be to use DIR to create a (sorted) file list but piping that into CKSUM would probably choke, too (since DOS is so brain dead). I'd really like to avoid writing some DOS-specific utility to do this as it seems like bogus code to maintain. I'd rather see *no* globbing and list everything explicitly... --don
