GT.M provides a compiler and run-time environment for the M language. Program development uses standard editors and utility programs.

GT.M requires minimal administrative effort.

M routines are stored as text files and object files in the native file system. Compilation of source text into object code is typically automatic, but may be invoked explicitly. A user may store routines in multiple libraries and/or directories organized into search hierarchies, and change the search paths as needed.

For more information on the GT.M language and programming environment, see GT.M Programmer's Guide.
