very early on, i wanted to demonstrate that rexx could be used as an application development language. the vm/cms dump processing facility was a few score k-lines of assembler with a dept. in endicott supporting it. i wanted to demonstrate that working half time over three months, i could use rexx to re-implement the facility from scratch with ten times the function and ten times the performance .... neat trick by itself for an interpreted language compared to pure assembler ... turns out part of the trick was a 120 line assembler stub routine used by dumprx for the actual interfacing to dump files. misc. collectes posts on the subject http://www.garlic.com/~lynn/subtopic.html#dumprx eventually, at one point it was in use by nearly all internal vm locations as well as vm PSRs. -- Anne & Lynn Wheeler | http://www.garlic.com/~lynn/
