Can anyone suggest suitable Cache ObjectScript syntax for open/use/read statements on a simple ms-dos text file.
I've tried various examples seen on the web but they appear to be implementation specific.
I used MSM MUMPS many years ago but am now retired & would like to write a few simple routines for my own amusement & mental challenge.
I am using the free Version of Cache (V 2017.1) on my Windows 10 PC. The installation file was CachePCkit_x64.exe
My apologies for this query being very basic.

Hi,

I know you're doing a big effort to build a new IDE in Eclipse ecosystem but Visual Studio Code is a new an even better and faster tool for coding... did you have any plans to release any COS extension for it in the near future? There you can already find extensions for all current more common progrmaming languages and it would be great to have COS as one of them.

Thanks

Rebuild class index

I have a class. In class there is an index. This index is for quick search on name property.

And there is also index global ^GLNameIndex(Name, userId) = ""

When I add new User entry through class, f. i.

S user = ##class(User).%New()
