Zebra Programming Language (ZPL) is a page description language from Zebra Technologies, used primarily for labeling applications. The original language was superseded by ZPL II, but it is not fully compatible with the older version. ZPL II is supported by some non-Zebra label printers. [1] [2]
ZPL uses the array abstraction to implement a data parallel programming model. This is the reason why ZPL achieves such good performance: having no parallel directives or other forms of explicit parallelism, ZPL exploits the operational trait that when aggregate computations are described in terms of arrays, many scalar operations must be (implicitly) performed to implement the array operations.
ZPL may refer to: ZPL (complexity), a complexity class; ZPL (programming language), for scientific applications; Zebra Programming Language, for label printers;

Programming in second generation languages may yield speed benefits, but several disadvantages have led to its decline: Programming is expressed in terms of individual processor instructions, rather than higher level logic. [2] [3] Low-level memory and hardware details must be manually managed which is often bug-prone. [2]
[8] [9] [10] Kathleen Booth developed Assembly Language in 1950 to make it easier to program the computers she worked on at Birkbeck College. [11] Grace Hopper and UNIVAC. Grace Hopper worked as one of the first programmers of the Harvard Mark I. [12] She later created a 500-page manual for the computer. [13]
John A. N. Lee was the conference chair and Sammet again was the program chair. In contrast to HOPL I, HOPL II included both invited papers and papers submitted in response to an open call. The scope also expanded. Where HOPL I had only papers on the early history of languages, HOPL II solicited contributions on: early history of specific languages
