'Introduce yourself is a pseudonatural esolang created by [[User:None1]]. ==Memory Model== Introduce yourself is based on variables that can store unbounded unsigned integers. ==Commands== There are these commands in Introduce yourself. {|class="wikitable" ! Command !! Meaning |- | <code>Hi, I am ''X'', I am ''Y'' years old.</code> || Creates a variable named ''X'' with a value of ''Y'', this command must be runexactly ''once'' for every variable. |- | <code>How old are you, ''X''?</code> || Outputs the value of the variable named ''X'', do nothing if it doesn't exist. |- | <code>How old are you in character, ''X''?</code> || Outputs the value of the variable named ''X'' modulo 256 as ASCII, do nothing if it doesn't exist. |- | <code>The age of ''X'' is now a secret.</code> || Reads an unsigned integer from user input and store it to the variable named ''X'', EOF returns 0, do nothing if it doesn't exist. |- | <code>The age of ''X'' is now a secret in character.</code> || Reads a character from user input and store its ASCII value to the variable named ''X'', EOF returns 0, do nothing if it doesn't exist. |- | <code>''X'': ''Y'' years later...</code> || Increases the variable named ''X'' by ''Y'' (an integer). |- | <code>''X'': ''Y'' years ago...</code> || Decreases the variable named ''X'' by ''Y'', if the result is less than zero, then ignore this command (an integer). |- | <code>Are you ''Y'' years old, ''X''?</code> || If the value of ''X'' isn't ''Y'', skip next instruction (if there is no next instruction, then terminate the program). |- | <code>Pardon me, please say line ''X'' again.</code> || Jump to line ''X'' (the first line is line 1). If the line number doesn't exist, then terminate the program |} Variable names can have be any character except whitespaces. Invalid commands raise a syntax error: Syntax error ==Examples== ===[[Hello World]]=== <pre> Hi, I am PzaV, I am 72 years old. How old are you in character, PzaV? Hi, I am DmFm, I am 101 years old. How old are you in character, DmFm? Hi, I am IlUu, I am 108 years old. How old are you in character, IlUu? Hi, I am ZSRN, I am 108 years old. How old are you in character, ZSRN? Hi, I am xL+0, I am 111 years old. How old are you in character, xL+0? Hi, I am R38C, I am 32 years old. How old are you in character, R38C? Hi, I am NJHl, I am 87 years old. How old are you in character, NJHl? Hi, I am Lukk, I am 111 years old. How old are you in character, Lukk? Hi, I am qfZl, I am 114 years old. How old are you in character, qfZl? Hi, I am sr/4, I am 108 years old. How old are you in character, sr/4? Hi, I am cmnk, I am 100 years old. How old are you in character, cmnk? </pre> ===[[Cat Program]]=== This program never terminates <pre> Hi, I am a, I am 0 years old. The age of a is now a secret in character. How old are you in character, a? Pardon me, please say line 2 again. </pre> Here is an alternative that terminates when EOF: <pre> Hi, I am a, I am 0 years old. The age of a is now a secret in character. How old are you in character, a? Are you 0 years old, a? Pardon me, please say line 7 again. Pardon me, please say line 2 again. </pre> ===[[Truth Machine]]=== <pre> Hi, I am a, I am 0 years old. The age of a is now a secret. How old are you, a? Are you 1 years old, a? Pardon me, please say line 3 again. </pre> ===[[Quine]]=== Syntax error ==Computational class== As shown in the article [[brainfuck]], when the tape is at least 3 cells long, and the cells can store integers of any size, [[brainfuck]] is Turing complete. As the integers in this esolang are unbounded, we can simply simulate [[brainfuck]] in this esolang. The following is the unfinished table of translation from [[brainfuck]]. {| class="wikitable" ! Introduce yourself !! [[brainfuck]] |- | <pre>Hi, I am p, I am 0 years old. Hi, I am a, I am 0 years old. Hi, I am b, I am 0 years old.
