Data set name variable substitution

For View, Edit, Select, Dslist and Rsearch commands or any of the Z Data Tools pull-down options, variable substitution is performed if the variable can be resolved within the current edit or view session. If the value in the window title has &variable names as a part of the string, Z Data Tools resolves the variables when you select a command that requires a valid data set name.

See the following example:
