Sorry, but this is variously wrong and misleading. 

-matsize- has nothing to do with the number of variables you can hold. 

There is an absolute limit on the number of variables each Stata can
hold and that is not affected by memory settings. 

See -help limits-.

You can increase your matsize and/or set memory to be larger and that
will allow you to increase your number of variables.

before you open your dataset,
set mem 100m
set matsize 800
