List of keywords

Normal keywords

Top level keywords

These keywords can occur at the top level of the file:

import segment
array struct union enum alias

Declaration modifiers

These keywords occur within variable, array and function declarations:

Variable declaration modifiers: const volatile register static stack
Function declaration modifiers: asm inline noinline interrupt kernal_interrupt macro reentrant extern
Array declaration modifiers: const
Common modifiers: segment align

Statement keywords

These keywords occur within function bodies:

if else for while do
goto label
asm
return

Sub-statement keywords

These keywords occur within bodies of certain other statements:

for-loop directions: to until downto parallelto paralleluntil
special return-dispatch branch: default
loop control flow: break continue

Contextual keywords

These are not considered keywords, but have special meaning in certain syntactical locations:

special alignment constant: fast
special array function: file
text encoding names: z defaultz scr scrz; for the rest, see the list of text encodings
default is also a name of a text encoding, but it's also a keyword

Reserved identifiers

Most of reserved identifiers are considered keywords (i.e. you cannot override them, even locally). Some are not, but overriding them is strongly discouraged and for highest code clarity should also be considered keywords.

The keyword status of those identifiers may change in the future.

Built-in types

The following identifiers are considered keywords:

byte ubyte sbyte word long
pointer void bool     
set_carry set_zero set_overflow set_negative    
clear_carry clear_zero clear_overflow clear_negative    
int16 int24 int32 int40 int 48 int56 int64 int72 int80 int88 int96 int104 int112 int120 int128    
unsigned8 signed8

farword is a deprecated alias for int24 and it is not a keyword. It will be removed in the future.

Built-in constants

The following identifiers are considered keywords:

true false

The following identifiers are not considered keywords:

nullptr nullchar

Built-in functions and operators

The following identifiers are considered keywords:

not hi lo nonet sizeof

The following identifiers are not considered keywords:

sin cos tan call

Reserved field names

It is not allowed to define a struct or a union with a field with any of the following names:

pointer addr rawaddr return

Preprocesor keywords
