INFO.TXT, was Re: [HECnet] UPDATE: HECNET.HLP file for VMS systems

I should probably make a manual HLP file for LEGATO, Bob you OK with that? LEGATO's INFO.TXT have real yucky file attributes and a real yucky file format. :-) (What on earth was used to produce it???) Stream_CR typically surfaces with files coming from WEENDOZE.

Expires: <none_specified> File protection: System:RE, Owner:RE, Group:RE, World:RE File organization: Sequential File attributes: Allocation=0 Record format: Stream-CR, no maximum defined Record attributes: Carriage return What does it mean if you have stream-CR and attribute Carriage Return? I mean, yes, each record is separated by a CR, and then what? Add an additional CR at the end of each line? "Record format" refers to the data in the file. Stream_CR means that the records are delineated with a <carriage-return> character. RMS will then populate its internal buffers and the user's buffer upon a $GET with the current record data up to the <carriage-return> character. RMS internal handlers discard this <carriage-return> and update the NRP (Next Record Pointer) leaving it pointing after the <carriage-return> to a subsequent (assuming there is one) record. "Record attributes" refer to how to present the record to the application that performed the $GET to read the record. With "Record attributes" set to "Carriage return", RMS will synthesize a record with <carriage-return> and <line-feed>. If the "Record format" is VFC (Variable Format Control), this synthesis is over-ruled by the format in the VFC header of each and every record. This is fugly. On VMS, I would typically read a file like this into TECO and then, EX (exit) to write out a new file that will have typical VMS RMS file attributes. $ EDITT/TECO <the-file> *EX$$ <-- the $ is echoed by TECO when entring an escape $ (ie. escape => CTRL-[) -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG Well I speak to machines with the voice of humanity.

Or some weird optimizations when building simh for Linux? After all, the Linux virtual machine runs rather native, so the slow down in that step is pretty minimal. Johnny

I don't think I've seen a developer "code" anything lower than Ruby or Python in years... I don't think Sunacle will let Java die. ;) In all fairness, he did say "we'll spend the next 50 years trying to get rid of it". I know someone that was trying to make an IRC bot in x86 ASM... I'll probably do one in PDP-11 assembler, just to spite you. :-) That would be impressive! Can't see why. I have an irc client which I think is less than 100 lines of C. Since I already have TCP/IP on my RSX system, doing an IRC client inspired by that C thing would be a piece of cake. I'll sit down and fix that tomorrow. Doing a bot as a next stop, once that is done, would be easy. You didn't ask that it would be any good, or do anything meaningful. :-) Johnny Johnny On Sat, Dec 29, 2012 at 3:15 PM, Johnny Billquist <bqt at softjar.se <mailto:bqt at softjar.se>> wrote: On 2012-12-29 20:55, Peter Lothberg wrote: But it is fun to see people fail. :-) It is definitely fun to watch people try to break in to VMS. ;) On Sol.Stupi.Se <http://sol.stupi.se/> (59.10) they think it understands X.86 binaries..
