Compatibility with earlier systems

Use of M functions
As in earlier versions, macro technology allows special M functions to be used instead of
language commands (compatibility).
The M functions and equivalent language commands as used in earlier systems are as
follows:
M20
M22
M25
M26
Note
M functions can be configured in machine data.
When M functions are assigned to language commands, it must be noted that M functions
are organized in auxiliary function groups.
