Stack based

Not to be confused with Stack-based.

Stack based is an esolang by User:ChuckEsoteric08 which is similiar to Queue based but it uses stack instead.

Specificstion

Stack based uses three stacks as memory: a, b and c

push x y

Push x to stack y

pop x

Pop from stack x

move x y

Pop element from stack x and push it to stack y

inp x

Push input to stack x

out x

Pop element from stack x and output that element

lbl x

Declare label x

rep x y z

Similiar to [abc_xyz] in Queue based. Replace every element in stack x which are equal to y with z

jmp x

Pop element from stack x and goto label which name is equal to popped element

rev x

Reverse stack x

Computational class

The language can be proven to be Turing-complete by this Bitwise Cyclic Tag interpreter:

lbl inpcode
inp a
rep a 0 inpcode0
rep a 1 inpcode1
rep a $ inpcodeend
jmp a
lbl inpcode0
push inpcode0 a
push inpcode a
jmp a
lbl inpcode1
push inpcode1 a
push inpcode a
jmp a
lbl inpcodeend
rev a
lbl inpdata
inp b
rep b 0 inpdata0
rep b 1 inpdata1
rep b $ inpdataend
jmp b
lbl inpdata0
push inpdata0 b
push inpdata b
jmp b
lbl inpdata1
push inpdata1 b
push inpdata b
jmp b
lbl inpdataend
rev b
rep b inpdata0 data0
rep b inpdata1 data1
lbl exec
rep a inpcode0 cmd0
rep a inpcode1 cmd1
jmp a
lbl cmd0
rev a
push cmd0
rev a
pop b
push exec a
jmp a
lbl cmd1
rev a
push cmd1
rev a
jmp b
lbl data0
push data0 b
push exec a
jmp a
lbl data1
push data1 b
rep a cmd0 next0
rep a cmd1 next1
jmp a
lbl next0
push next0 a
rev b
push data0 b
rev b
push exec a
jmp a
lbl next1
push next1 a
rev b
push data1 b
rev b
push exec a
jmp a

Input Program character by character, then input $ and then input data also character by character and then input $.
