A-Shell Reference

Indicates that setdef contains a list of all the allowable characters. To be accepted, input characters must first pass the normal type code acceptance rules, and then must be listed within the setdef string. Consequently, to use setdef exclusively to specify the allowable characters, combine type codes { and A. Note that upper and lower case is significant when setdef is used this way. See the setdef topic.
