DATA [pet] [vic20] [c64] [c16] [cplus4] [c128] [x16] [m65] The DATA directive puts numeric or string literal values at the memory area where it is used. Syntax DATA [AS ] [, ...] If AS is omitted, the default BYTE type will be used.

CONST - [Syntax]

neils (neils@undisclosed.example.com) — 2026-10-08T18:04:11+00:00

CONST [pet] [vic20] [c64] [c16] [cplus4] [c128] [x16] [m65] The const directive defines a constant. Constants are named values that exist in compile-time only and are replaced with their numeric value in runtime. Syntax [SHARED] CONST [AS ] =

Commander X16 support XC=BASIC can compile programs to the Commander X16. Everything that has been part of the core language is ported to the [x16], including sprites, sound and interrupts. In addition, a new library is available to the user to exploit some of the additional features that this machine offers.

OPTION - [Examples]

neils (neils@undisclosed.example.com) — 2026-10-08T17:45:54+00:00

OPTION The OPTION directive sets various compilation options. Most of these options can be set from the command line as well. The OPTION directive gets higher priority than command line options. Syntax OPTION [= ] Examples

INCBIN - [Syntax]

neils (neils@undisclosed.example.com) — 2026-10-08T17:44:19+00:00

INCBIN [pet] [vic20] [c64] [c16] [cplus4] [c128] [x16] [m65] Include raw binary data in the compiled program. Syntax INCBIN "path/to/binary_file" [, ] The INCBIN directive instructs the assembler to include a custom binary file. This is useful to include graphics, music or any kind of data - even machine code routines - in your program. The included file must be a path relative to the folder where the code module is.

LOCATE - [LOCATE]

neils (neils@undisclosed.example.com) — 2026-10-08T17:42:17+00:00

LOCATE [pet] [vic20] [c64] [c16] [cplus4] [c128] [x16] [m65] The LOCATE command is used to set the cursor position. Syntax LOCATE ,

Subroutines - [Static Variables Inside Dynamic Subroutines]

neils (neils@undisclosed.example.com) — 2026-10-08T17:41:14+00:00

Subroutines While you can use the GOSUB command in pair with RETURN to call parts of code as subroutines, the more sophisticated way of implementing subroutines is using the SUB ... END SUB block. Defining Subroutines Subroutines are named routines that accept zero or more arguments. The simplest syntax to define a subroutine is the following:

Control Flow Statements - [Multiple branching]

neils (neils@undisclosed.example.com) — 2026-10-08T17:34:51+00:00

Control Flow Statements Conditional branching With the IF statement you can test a condition and then run code based on whether the condition test passed or failed. IF THEN END IF The IF clause runs the statements under it when the

Arithmetic expressions

neils (neils@undisclosed.example.com) — 2026-10-08T17:29:40+00:00

Arithmetic expressions When no parentheses are present, arithmetic expressions are evaluated from left to right, with multiplication and division having a higher priority than addition and subtraction. The following table explains operator precedence in XC=BASIC:

Variables - [Implicit Definition]

neils (neils@undisclosed.example.com) — 2026-10-08T17:28:43+00:00

Variables XC=BASIC is a statically typed programming language which means that the type of a variable is known at compile time. All variables have a type and that type cannot change. Defining Variables In an XC=BASIC program, all variables must be defined before they're used. Either you define them using the

Installation and Usage - [Installation]

neils (neils@undisclosed.example.com) — 2026-10-08T17:23:07+00:00

Installation and Usage Prerequisites * XC=BASIC is a console application and therefore you need to understand at least the very basics of using the console of your choice, e. g. executing commands, changing directories, copying files, etc. * XC=BASIC depends on
