Article Robert Cemper · Jul 4, 2020 4m read Editor Archaeology During the development of the Terminal Multi-Line Command Editor I discovered in my IRIS installationa piece of software that I just can classify as a historic artifact. And it is still fully operational !!! As it dates back to times before InterSystems was founded in 1978 you may understand my surprise.I personally stepped into that environment in 1978 and used it then for daily work. #Other 16 5 0 399
Article Robert Cemper · Nov 11, 2017 3m read Summary on Local Variable Scoping This should be an overview over a subject that pops up over several places in online documentation mostly as remarks and never as dedicated chapter. Once upon a time ... No it's not a fairy tale.In the beginning of Caché (and before) you had your partition to run your code. Part of that partition was a space with all your local variables nicely sorted by %,A,..Z,a,...z #Beginner #Caché #InterSystems IRIS 14 3 1 1.2K
Article Robert Cemper · Oct 15, 2017 3m read @Indirection and eXECUTE - why ? As I mentioned in an early post the roots of COS were laid in the late 60ies of the 20th century. Close to that time, BLISS was designed at Carnegie-Mellon University (January 15, 1970)https://en.wikipedia.org/wiki/BLISSSimilarly in 1972 C language was written at Bell Labs.https://www.bell-labs.com/usr/dmr/www/chist.html #Caché #InterSystems IRIS 12 2 0 987
Article Robert Cemper · Aug 26, 2017 3m read From The Roots to InterSystems This is a rather personal view of the history before Caché.It is in no sense meant to compete with the excellent books from Mike Kadow discussed in an earlier article.We have different histories and so this is meant to create a different perspective of the past. #Caché #InterSystems IRIS 38 15 2 2.2K
