An experimental full screen editor has been written in APL for IBM 3270 display terminals, based on the following principles: • a small command repertoire, based on APL syntax • an undo facility for correcting mistakes • internal dependence upon a small number of editing primitives As written, the editor contains two major commands,(More)
APL includes a few primitives to permit searching of strings for single characters, principally the dyadic iota. APL2 adds iota underline. This latter function will find all occurrences of a given string in a longer string. Sometimes, however, more elaborate searching is needed; for example, searching for strings of variable length, searching for any of(More)

The VM/SP System Editor XEDIT is used to edit APL objects. Two approaches are possible: with an APL function, or with an exec written in REXX (the new VM/SP System Interpreter). The advantages of the latter are that nothing need be copied into the user's workspace, and that APL code can be executed from XEDIT, and XEDIT commands from APL. No new Auxiliary(More)
Several computers have been built experimentally which incorporate a large number of identical CPUs. One example known to this author contains 65 identical microprocessors: one is the “master” and issues orders (normally identical or nearly so) to the other 64, called “slaves”. The master and each slave has its own storage unit. It(More)
