In this question each answer will get a "toolbox" that can be used to construct a program/function. The toolbox will consist of two things:

  • a list of programming languages

  • a list of valid characters

You must write a valid program/function in one of the languages provided using only the characters in the toolbox. Your program/function should output the number of answers already present on this question.

Once you have written and posted an answer the language and characters you have used will be removed from the toolbox and 1 new language and 12 new characters will be randomly added to be used as the toolbox for the next answer.

Rules

  • Each answer will:

    • Output the number of valid answers coming before it
    • Contain a subset of the characters provided in the toolbox for that answer. (repeats are allowed)
    • Be in one of the languages from the provided toolbox

  • The next toolbox will determined by this python program. To generate the next toolbox put in the remaining languages and characters along with the post id of the last answer.

  • The language list here is all the languages available on try it online at the time of this post. The characters have char codes 0-127.

  • You may write either a full program or a function as your answer. Since REPLs are different languages they will not be allowed. (use the TIO version of every language)

  • If a language uses a special encoding the characters should be interpreted as bytes (decoded from ASCII and padded with a zero).

  • The starting toolbox will be randomized from this questions post id (126063), there will be 7 languages to start and I will add the characters echoprint0 and ascii 0-31 for free to get people started.

  • You may not answer twice in a row

Scoring

Each person will have a score equal to the number valid answers they have provided. There will not necessarily be an end and I will not be accepting any answers.

Sporting

This is a competition, but I encourage you to put fun above winning while still staying competitive (if I could make the winning criteria "fun had" I would). Some things that are not fun:

  • Intentionally using characters you don't need to stunt future answers.
  • Attempting to game the post id system to make future tool boxes harder to use.
  • Attempting to game the post id system to make future tool boxes easier to use.

I can't prevent any one from doing these things, but I will be downvoting any answers I suspect are doing this.

On a more positive note, here are some things that are good sporting and encouraged:

  • Coordinating with other users in chat.
  • Saving characters for harder or more restrictive languages

    \$\begingroup\$ Well...an interesting setup that got nipped in the bud early due to too many missing characters for languages that are defined by a very small set of characters. Logicode got hosed by the lack of a 1 and ! in its toolbox. I managed to produce the string "0110" using ?,0 and + although I couldn't quite figure out what the ? actually did (and it was not in the language specification). But + was missing from the toolbox as well, along with = which would have allowed for variable assignment. Aaanndd...no o for output. \$\endgroup\$

There is a convert-to-ascii, but without an = you can't assign ?+?+?+0-like expressions to a variable to convert, nor can you wrap in parenthesis, due to a lack of (. ?+?+?+0 by itself is valid code...but produces no output. + is also missing, so even that won't work... \$\endgroup\$

Explanation

I don't really know Assembly as, and information online seems hard to find ,so this is modified from the Hello World test on TIO.

The main issue here is that we lack the 2 byte, (turns out we did, but hey looks like I saved a 2 for the next answer) this makes it relatively hard to print 26. We can't use raw ascii or even Hexadecimal (0x32) so I ended up using binary.

msg:
.byte 0b110010,0b110110

Tells it to output the two bytes 2 and 6.

I've never used or even heard of ELF before, so this one was an adventure to figure out. I eventually copied much of Dennis' 32 bit Hello, World! program (64 bit version here). I modified it to print 33 and was able to remove a line of bytes.

30. Visual Basic .NET (Mono), 9 bytes

MSGBOX 29

Pops up a system dialog box containing 29. Very similar to alert in javascript. It is case insensitive, but is usually written as MsgBox.

This can't be tested on TIO because MsgBox is a system window and that can't be seen online. The easiest way to test it is by pasting the code into a .vbs text file and running it on Windows. A .vbs file uses VBScript, a scripting version of VB that is very similar (MsgBox is the same between the two).

It's fun to use MsgBox again as that was the very first thing I ever programmed. In fifth grade, I made a series of MsgBox scripts to mess with friends.
