MIIS/MUMPS

Magic got it start from MUMPS and MIIS. MUMPS actually was built to stop on errors in its tracks and report errors, from what i understand MIIS was built to keep trucking along.

Use Notepad software to edit Meditech code

This is a notepad program called programmers notepad, using the visual basic layout you can get a match on the "{" which will save you time. Try either the vb or C+ setting, to get the best result. Good programming!

Error messages in Meditech

Error information is stored in A symbol table by the OS immediately upon error:

["AA"] or ["A"]A= Line of code error was encountered
["AB"] or ["A"]B= Error Location
["AC"] or ["A"]C= Machine Node
["AD"]or ["A"]D= Program Block

Using Nill to Delete structures instead of Kill command

It is a safer practice to use the following routine when you need to delete a structure instead of using the K command.

so if the structure looked like this

:["LUNCH","APPLE"]
:["LUNCH","COKE"]
:["LUNCH","HOT DOG"]

"LUNCH"^A,""^B,DO{>:[A,B]^B ""^:[A,B]}

Performing a physical next on the structure and placing a value in A will delete everything in "LUNCH".

Way to save prefixes in /

1. Seg over to directory
2. Open the prefix to \S
O(\S,%.MIS.dic[mis.dbase,"MIS"]),C($U,%U),

3. use Z.fpn to save this value to a / value
%Z.fpn(^\)^/OPEN.MIS.DIC

4. Then you can use this open
O(\S,/OPEN.MIS.DIC)
