TALK is a typed assembly language which is flexible and expressive enough to implement important OS facilities, such as memory management (e.g., malloc/free) and multi-thread management.

The "assembler" just emits binary executables annotated with type information. It does not perform type-checks.
The type-check is performed by the "verifier".


We are sorry but we have not prepared any user manual of TALK. (Please see the programs in TOS at this time)
