APL.SV
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.
