SET

Sets a instruction to value.

Input stack: v w

Output stack:

Since it is rather bothersome to keep certain values (like handles or strings) around by manipulating the stack, it'd be nice to be able to refer to them directly.

SET allows to define a value of a instruction for the scope of the script's remainder.

SET will put the second topmost item off the stack (v) into the instruction referenced by top item (w)

PumpkinDB> "key" 'key SET [`key "value" ASSOC COMMIT] WRITE [key RETR] READ
"value"

Allocation

Allocates on the heap for the binary form definition.

Errors

EmptyStack error if there are less than two items on the stack

It will error if the format of the instruction is incorrect

It may error if this instruction is a built-in instruction that was previously defined.

Tests

works : 1 'val SET 1 val.
empty_stack : [SET] TRY UNWRAP 0x04 EQUAL?.
empty_stack_1 : ['a SET] TRY UNWRAP 0x04 EQUAL?.
