26.0. "TEX fails after SET DEFAULT <dir>" by HAM::HOFFMANN () Wed Feb 25 1987 17:04

	Here's another nice little problem for you to look at ...
	It took me quite a while to figure out what was happening:

	When using anglebrackets to set the default directory, like
	shown in this example:

		$ SET DEFAULT <HOFFMANN.DOCUMENT.DEMO>

	then TEX will fail to locate input files (which ever).

26.1Yes it does (sigh).CLOSET::PARMENTERThu Feb 26 1987 16:135
    Hmmmm.  We thought we had fixed that.  Thank you for spotting the
    problem, I will add it to the list of TeX bugs.

26.2Why <>?VAXUUM::KOHLBRENNERTue Mar 03 1987 12:056
    Why do you use angle brackets instead of square brackets?
    
    (I know they're legal, so I am not arguing against their
     use, I'm just curious as to why anyone would use them.)

>>>    Why do you use angle brackets instead of square brackets?
    
Well, here in europe, a lot of people set their VT200's to
"TYPEWRITE KEYS"-mode (the usual is "DATAPROCESSING KEYS").
In this mode you don't get square brackets easily. You'll have
to know the "compose-character"-feature very well to find them.

Reason for changing to TYPEWRITER-KEYS is the support for specials
like Umlaute (in germany) ...

On the other hand, I think I saw a note a couple of month ago, where
replaceing square-brackets with angle-brackets as the VMS-default
was considered for VMS-V5 or later!

26.4A holdover from the past?ATLAST::BOUKNIGHTEverything has an outlineTue Mar 03 1987 14:528
    <> were the directory characters for DECsystem 10/20s longtime ago,
    if memory serves me, and were included to make transition of users
    from TOPS to VMS easier.  Some one correct me if I'm wrong.
    
    You can also use the period to separate the version number from
    the file extension for the same reason, I believe.

26.5TOPS20 uses <>, TOPS10 prefers []HAM::HOFFMANNTue Mar 03 1987 17:004
	almost jack, you're right about TOPS20, but TOPS10 has its
	PPNs in square brackets.

26.6There are reasonsCLOSET::KAIKOWTue Mar 17 1987 19:3017
re: 26.2

Although the answer to 26.2 is implied by other replies, I feel duty bound to
state the following:

1. VMS does not support <> in addition to [] because  earlier DEC Systems 
   do/did,  rather [] have international graphic problems in ISO 646 (the ISO
   "equivalent" to ASCII).

   We need <> to sell in other countries, perhaps [] should NEVER be used.

2. A new ISO standard for 8-bit codes has been, or will shortly be, approved
   that has straight ASCII in positions 0-127.

   In time this will eliminate the problem of such international graphic
   representations. However, for conformance and political reasons, this will
   not happen overnight.
