APL.SV, "APL with Shared Variables", was an enhancement to APL\360 released by IBM in 1973. As the name suggests, APL.SV introduced the concept of a shared variable which could be used by multiple processes. It also included system variables as a kind of shared variable, and system functions. APL.SV also introduced the Format and Execute functions, and the Scan operator.

The enhancements to APL described herein are the result of more than six years of personal experience with APL\360, and countless comments and suggestions from many other users. The shared variable concept goes back in principle to early publication by Falkoff and Iverson, but is was R. H. Lathwell who recognized the practical potential of the idea and, with L. A. Morrow, designed an effective data processing facility based upon it. The system was implemented by Lathwell, Morrow, J. A. Brown, and C. F. Shen, all of whom contributed to the design of the other new features as well. R. J. Creasy first proposed the use of surrogate names.
