How to compile class routines with mapped modifier

InterSystems FAQ rubric

To compile class routines including the mapped modifier, specify the compiler modifier "/mapped=1" or "/mapped". For example, do the following:

[Example 1] Get the class list and compile 

 do $System.OBJ.GetClassList(.list,"/mapped")
 // build your classes starting from .list
 do $System.OBJ.Compile(.list) 

[Example 2] Compile all classes 

 do $system.OBJ.CompileAll("/mapped")
