The syntax used in the inline assembler is inspired by the Intel assembly language. This means that each statement has the form: <op> <dest>, <src>;. Some statements only take one operand.

Each of the two operands can be one of:


Three different registers are available: a, b and c. These come in four sizes, al, bl and cl for byte-sized registers, eax, ebx and ecx for Int-sized registers, rax, rbx, rcx for Long-sized registers and ptrA, ptrB and ptrC for pointer-sized registers. These are referred to by their names.


Literals are numeric constants with a prefix telling their type. Size prefixes are supported: b for Byte, i for Int, n for Nat, l for Long , w for Word or p for pointer-size.


To refer to variables in Basic Storm, simply refer to them by name. A variable will return its representation in Basic Storm. A variable holding an Int can be accessed as an Int in assembler and modified. Variables of object-types are pointers.


Labels can be placed before or after any statement, and are formed by a name followed by a colon (:). Labels are referred to as @<name>.


Some op-codes take a conditional as one of their parameters. A conditional represents the result of the last cmp operation. These conditionals can be one of the following:
