Sceql
From Esolang
Sceql is a language that provides a single byte queue as the only form of memory available to programs. The queue can never be empty, and data can never be removed from it once enqueued into it. Initially the queue has one value of 0.
[edit] Instructions
= NEXT Dequeue a byte and enqueue it again
- DEC Decrement the byte that would be dequeued next (wrapping)
_ INC Increment the byte that would be dequeued next (wrapping)
\ BEGIN Skip to the instruction after the corresponding END if the byte
that would be dequeued next is zero
/ END Go back to the corresponding BEGIN
! GROW Enqueue a new zero byte
& INPUT Read a byte from stdin and enqueue it (0 for EOF)
* OUTPUT Dequeue a byte, write it to stdout, and enqueue it again
[edit] History
Sceql is a revised version of Qdeql. The instruction set is a lot more practical and easier to use than in Qdeql.
