No, you cannot. However, someone familiar with the macro language could either modify macro MABC to accept a list rather than a single variable, or write a new maco to repeatedly call MABC.

Depending on what MABC does, these approaches may be equally effective. However, if MABC modifies a single variable in a dataset with many observations, it would save a great deal of I/O to modify the macro to change several variables. Depending on the costs of CPU and programmer time, it may be less expensive to simply pass the data many times.
