Inspired heavily by this Wikipedia page: https://en.wikipedia.org/wiki/Tiny_BASIC

Still a prototype, make sure to report mistakes and bugs please

Usage of the command line:
Enter a command to run it immediately
Enter a line number, a space and then a command to store it at that line in the code (for example "4 PRINT A")
Enter RUN to start execution at line 0

Variables are capital letters from A to Z
Supported expression operations: +, -, *, /
Expressions support square brackets for grouping

Convenience features:

• P is an alias for the PRINT command,
• The usual equal sign in LET is omitted,
• The usual "THEN" in IF is omitted,
• The backslash '\' interrupts a running program,
• Use the DEBUG command to toggle printing the code as it runs,
• Use square brackets instead of normal ones to avoid having to press shift,
• Use single quotes (') instead of double ones for the same reason as above

Note, that:

• Available lines are 0 to 99,
• Gaps of 10 between line numbers like often done in BASIC are not recommended,
• An END command in the code will speed up exiting,
• Expressions should not contain spaces,
• Only non-negative integers are supported so far,
• Strings are only supported by PRINT,
• Not all mistakes in your code will cause an error

Keyboard layout reminder:

'+' is shift + '='

'*' is shift + '8'

'<' and '>' are shift + ',' and '.' respectively

Commands:

PRINT (list of exprs and strings)
Displays results of expressions and/or strings
Can be abbreviated as P
Examples:
PRINT 'Hi!'
PRINT A
PRINT 10-5
P 'Result:',C,[D-1]*2

LET (var) (expr)
Stores expression result in variable
Examples:
LET X X+1
LET H 10

IF (expr)(comparison)(expr) (command)
Executes command if comparison is true
Comparison operators: =, !=, <, >, <=, >=
Examples:
IF A+1>B PRINT 'YES'
IF B!=10 GOTO 5

GOTO (expr)
Continues execution at given line

GOSUB (expr)
Calls the subroutine at given line

INPUT (list of vars)
Asks for the values each of the variables
Examples:
INPUT Z
INPUT A,B,C

PLOT (x expr) (y expr)
Puts a white pixel at given position

PEEK (var) (addr expr)
Stores value from memory address to variable

POKE (addr expr) (expr)
Stores value into memory at address

RETURN
Returns from subroutine

LIST
Displays the program lines

DEBUG
Toggles printing currently executed line as the program runs

ERASE
Erases the program

CLEAR
Resets all variables to 0

END
Returns to the command line

Thanks :)
No repository with the code yet though
