01:41:40 <esolangs> [[Headsecks]] M https://esolangs.org/w/index.php?diff=116397&oldid=115814 * Kaveh Yousefi * (-1) Rectified an orthographic mistake.
05:48:30 <Sgeo> There exists at least one non-esoteric programming language in which the syntax to indicate that the rest of the line is a comment is: two spaces
05:57:13 <int-e> . o O ( "we hate indentation" )
05:57:33 <zzo38> Which programming languages is that?
06:00:08 <Sgeo> IBM 1401 Autocoder
06:00:40 <Sgeo> A remark can be included anywhere in the operand
06:00:40 <Sgeo> field of an Autocoder statement, if at least two nonSignificant spaces separate it from the operands.
06:00:45 <Sgeo> According to http://bitsavers.org/pdf/ibm/1401/J24-1434-2_IBM_1401_Autocoder_Specifications_1961.pdf
06:01:45 <Sgeo> The programs would generally be written down on a sheet that shows the exact columns each character is in, and then typed into punched cards, so I'd imagine two spaces is more clearly visible than they would be in a modern day text editor
06:10:43 -!- tromp has joined.
06:11:26 <citrons> is this just a macro assembler
06:13:08 <citrons> wow, strings are delimited with @
06:17:59 <int-e> Oh yes, designing for punched cards makes a difference.
06:19:21 -!- Deepfriedice has joined.
06:20:49 <citrons> putting things in specific columns, etc
06:20:52 <int-e> @ looks a bit like a colon on a punched card going by https://en.wikipedia.org/wiki/File:Blue-punch-card-front-horiz_top-char-contrast-stretched.png
06:21:50 <int-e> also, who really uses @ for anything, right
06:24:17 <int-e> (I'm assuming that 1961 is the date of that specification)
06:25:48 <zzo38> The document said you can have blanks and @ inside of a alphamerical literal, as long as @ does not appear in any comment on the same line as a alphamerical literal.
06:27:46 <zzo38> It also says only one alphamerical literal per line, which makes sense otherwise it would be ambiguous.
06:28:04 <citrons> I'm wondering what "processing overlap" is
06:28:45 <Sgeo> Offhand I think it's like async I/O, but let me check
06:30:25 <Sgeo> The processing overlap feature allows processing to
06:30:25 <Sgeo> be interrupted in order to take input-output cycles. A
06:30:25 <Sgeo> character can be read, written, or punched between
06:30:25 <Sgeo> processing cycles.
06:30:29 <Sgeo> http://bitsavers.trailing-edge.com/pdf/ibm/1401/A24-1403-5_1401_Reference_Apr62.pdf
06:30:50 <zzo38> It seems badly designed to use the same @ sign for overlap operations which can then interfere in this way.
06:31:00 <citrons> I was thinking the same thing
06:31:50 <citrons> what character set did the 1401 use?
06:31:55 <Sgeo> @ for overlap seems to be machine code level, while Autocoder is assembler (before the term "assembler" was invented)
06:32:18 <Sgeo> Something based on BCD based on Hollerith, I think
06:32:43 <Sgeo> Although the punched card format doesn't quite match the internal format
06:33:18 <citrons> an "@" appears literally in the machine code?
06:33:38 <Sgeo> Hmm, "assembler" does exist before 1959
06:33:46 <Sgeo> 1401 machine code is human readable
06:34:06 <citrons> oh, there's a chart in this document
06:34:09 <int-e> it would be stored on punched cards
06:34:40 <Sgeo> https://ibm-1401.info/1401CardDecks-RandyT/MusicGeneralProgramobject.txt
06:34:49 <citrons> oh, right. if you don't have an assembler, I suppose you'd have to write machine code directly.
06:35:14 <citrons> wow, that's just wonderful.
06:35:38 <Sgeo> The character set doesn't match ASCII. There are stuff like lozenges. This site, for some reason, shows these text files as the old encoding SIMH used to use, except ` instead of ' for some reason
06:35:49 <Sgeo> https://www.righto.com/2019/09/risky-line-printer-music-on-vintage-ibm.html
06:36:00 <int-e> Hah the Autocoder specification itself also has a mapping from mnemonics to opcodes.
06:36:18 <int-e> Sgeo: oh right you wanted to emulate that
06:37:13 <int-e> maybe the term "macro assembler" wasn't coined yet
06:37:18 <Sgeo> Here's the current status of my emulation attempt: https://cdn.discordapp.com/attachments/751238054823329863/1152156688619675658/marsiellaise2.wav is the attempted emulation, https://www.youtube.com/watch?v=Oe0MGO17K10 is the real thing
06:38:02 <int-e> Or maybe it's just the usual phenomenon that early on the same thing gets called different names by different people before eventually a field standardizes the terminology.
06:40:30 <Sgeo> Sense Switch A is weirdly fascinating. Like turning off the ability to check for EOF
06:41:03 -!- siesta has quit (Quit: Connection closed for inactivity).
06:41:49 <int-e> so did they have support people who'd take those sheets and operate the card punchers?
06:42:20 <int-e> (and did those punchers have autoincrement features for line numbers?)
06:42:53 <int-e> (and maybe a repeat feature for the identification too... hmm)
06:43:46 <Sgeo> The punchers had some automated features, not sure if autoincrement is in there. But automatically filling in some stuff, and skipping to the next field, is
06:44:06 <int-e> it's almost surreal from today's perspective... we take displays for granted
06:44:30 <int-e> and, well, computers, obviously
06:44:59 <int-e> tabs are a mechanical typewriter feature
06:45:19 <Sgeo> https://www.youtube.com/watch?v=Q07PhW5sCEk computing with no displays, but work in progress of being able to interact with a computer without wasting valuable computer time
06:45:20 <int-e> so it would be surprising if the punched card analog didn't have that :)
06:46:16 <int-e> hmm, that's kind of long, maybe another time
06:48:45 <Sgeo> Notes. Sense switch A (last card switch) is standard
06:48:45 <Sgeo> in all systems equipped with an IBM 1402 Card
06:48:45 <Sgeo> Rea -Punch. When the last card passes the second
06:48:45 <Sgeo> reading brushes, and switch A is in the ON position,
06:48:45 <Sgeo> the last-card indicator is turned ON and a Jl xxx A
06:48:46 <Sgeo> instruction causes a branch to the I-address. It is
06:48:48 <Sgeo> turned OFF: on a run-in; if the switch is physically
06:48:50 <Sgeo> turned OFF; or if the start reset key is pressed.
