Thanks a lot @Nigel.Salm5021 !
This matches my expectations I have from "Robotics".
Some solutions, that are used in real life.

Robots running around, serving tea, playing chess or tic-tac-toe  running on 2 or 4 feet or barking and singing are just toys to me. Nice for kids, nice for movies but totally useless in real life. Just a mimic copying humans or pets.

Class Documentation of %Library.RoutineIndex tells me:
property Type as %String [ Required ];

The type of routine, this will be one of:
  • MAC - Macro routine, content is stored in ^rMAC global
  • INT - ObjectScript routine, content is stored in ^ROUTINE global
  • INC - Include file, these may be included from a MAC routine, content is stored in ^rINC
  • BAS - Cache Basic routine, content is stored in the ^ROUTINE global
  • MVB - MultiValue Basic routine, content is stored in the ^ROUTINE global
  • OBJ - Object code, content is stored in ^rOBJ global

Class Documentation of %Library.Routine explains the storage and  tells me: 
• classMethode GetRoutineGlobals(ByRef Names As %String) as %Status

Return list of globals where routine and class information is stored.
Returns Names="ROUTINE,rBACKUP,rINC,rINCSAVE,rINDEX,rMAC,rMACSAVE,rMAP,rOBJ,oddDEF"
Here is some documentation on the format of the routine globals. ROUTINE - Native .INT COS code, generated from .MAC, or generated from classes. When compiled generates .OBJ code.
ROUTINE(Name,0)=timestamp when last saved
ROUTINE(Name,0,0)=# lines in routine
ROUTINE(Name,0,1...x) = Source Lines in routine
ROUTINE(Name,0,"GENERATED")= 0/1 whether routine is generated or native
ROUTINE(Name,0,"INC",IncludeFileName1)=Timestamp when last include file last saved
ROUTINE(Name,0,"INC",IncludeFileName2)=Timestamp when last include file last saved
ROUTINE(Name,0,"SIZE")=# bytes in routine
ROUTINE(Name,0,"LANG")=language mode ROUTINE(Name,"MAC")=Timestamp of .MAC code when last saved if generated
rBACKUP(Name,Type,version) - backup of ^ROUTINE, created by the command Merge ^rBACKUP(rtn,type,nextverersion)=^ROUTINE(rtn) where type="INT/MVI/BAS" rINC - Native .INT or macro code, compiled into .MAC when included with #include directive
rINC(Name,0)=timestamp when last saved
rINC(Name,0,0)=# lines in include file
rINC(Name,0,1...x) = Source Lines in include file
rINC(Name,0,"SIZE")=# bytes in include file
rINC("ZZ","P") - Meta data used for precompiling include files rINCSAVE - Backup of ^rINC, created by the command Merge ^rINCSAVE(rtn,nextver)=^rINC(rtn,0) rINDEX - Index of .OBJ, .INT, and .MAC routines
rINDEX(Name,"OBJ/MAC/INC")=$lb(Time compiled,Size)
rINDEX(Name,"INT")=$lb(Time compiled,Size,Generated 0/1) rMAC - Native .MAC Macro code which when compiled generates .INT code
rMAC(Name,0)=Timestamp when last saved
rMAC(Name,0,0)=#lines in routine
rMAC(Name,0,1...x) = Source Lines in routine
rMAC(Name,0,"SIZE")=# bytes in routine rMACSAVE(Name,Type,version) - backup of ^rMAC, created by the command Merge ^rMACSAVE(rtn,nextver)=^rMAC(rtn,0) rMAP - Debug map used by the debugger and for error trapping
rMAP(Name,"INT","MAC",offsets)=$lb(debuginfo)
rMAP(Name,"MAC","INT",offsets)=$lb(debuginfo) rOBJ - Compiled .INT code
rOBJ(Name,"INT")=timestamp of .INT code when compiled
rOBJ(Name,0...n)=Compiled object code oddDEF - Source code for classes
oddDEF($zcvt(Name,"U"),....)=source code from class. Note that all of the other odd* nodes are meta data describing the class, and can be recreated by compiling the class. The rINDEXCLASS and rINDEXSQL nodes also get recreated when compiling the class.

so you may either do a query or just look into the globals directly
the sequence MAC        -> INT           -> OBJ      is
equivalent to modified -> modified - > compiled

No doubt, that it is a great environment for what I classify as ARTISTS.
But consider the maintenance of such ARTWORK.
It is a painful to impossible exercise to find and educate someone to replace a lost ARTIST.
Think of the masterpieces of the Italian Renaissance whether in sculpture or in painting.
We just don't understand the incredible technique they used.
Most famous case: Leonardo Da Vinci's "Last Supper" in Milan.
It is broken and just a shadow is left. Up to now, nobody was able to fix it in an acceptable way
