New A-Shell command line switch -erz <path> allows you to specify a file containing ersatz device definitions to be processed prior to any ERSATZ= statement(s) in the miame.ini file, regardless of whether the -erz switch comes before or after the -ini switch. <path> should be in native syntax, for example:

ashell -i /vm/miame/miame.ini -erz /vm/env1/test.erz

This is intended to be a convenience in situations where you have multiple environments which could share a miame.ini file except for the ersatz definitions.

Note that when there two or more definitions for the same ersatz device, the first one defined will take precedence. So any ersatz definitions in the file specified by the -erz command line will take precedence over any subsequent definitions.
