Literals and initializers

Numeric literals

Decimal: 1, 10

Binary: %0101, 0b101001

Quaternary: 0q2131

Octal: 0o172

Hexadecimal: $D323, 0x2a2

String literals

String literals are surrounded with double quotes and followed by the name of the encoding:

"this is a string" ascii

Characters between the quotes are interpreted literally, there are no ways to escape special characters or quotes.

Currently available encodings:

  • ascii – standard ASCII

  • pet or petscii – PETSCII (ASCII-like character set used by Commodore machines)

  • scr – Commodore screencodes

When programming for Commodore, use pet for strings you're printing using standard I/O routines and scr for strings you're copying to screen memory directly.

Array initialisers

An array is initialized with either a string literal, or a list of byte literals and strings, surrounded by brackets:

array a = [1, 2]
array b = "----" scr
array c = ["hello world!" ascii, 13]

Trailing commas ([1, 2,]) are not allowed.
