For the record, both [] and <> will work on TOPS-20 for directory names. Brackets [] are naturally preferable because they don't require a shift, which is much more comfortable when typing quickly.

Indeed. You can also use <> instead of [] as directory brackets. All because of confusion within DEC at the time when they tried to decide on a standard for all DEC OSes. (Because of this confusion, TOPS-20 changed it's syntax to be <> and ., but then VMS reverted the decision, but in the end they had to allow both variants, to keep something like compatibility between VMS and TOPS-20. RSX also allows the same.) Johnny
