Sussenguth|Ed Sussenguth]]. This was followed by a series of implementation efforts, first the relatively independent [[PAT]] first running in 1964, then the more APL-like [[IVSYS/7090]] interpreter in 1965 and finally the highly successful [[APL\360]] in 1966. The conflict with IBM's promotion of [[wikipedia:PL/I|PL/I]] delayed APL\360's release as a product and it was used only within IBM and in a few academic installations initially. It was released in 1968, preceded by [[APL\1130]], which had been made available earlier that year. In the explosion of [[time-sharing]] APLs that followed, IBM continued to direct language development with enhancements to APL\360 up to the release of [[APL.SV]] in 1973, although [[APL*PLUS]] offered more advanced system functionality. [[VS APL]], released in 1976, added file-system interaction. APL.SV's primitive set became a widely used standard for flat APLs, and was not extended further. However, [[Jim Brown]] was tasked with designing a [[Nested array model|nested]] successor beginning in 1971. [[APL2]], released in 1984 following a prototype Installed User Program (IUP) made public in 1982, was IBM's final APL design.</ins></div></td></tr>
