You can increase the efficiency of a program by filing frequently-used groups of statements separately and calling them up as and when they are required.

Parts of Quantum programs can be filed and included at the appropriate position in the main Quantum program. Entire blocks of axes and table control statements can be filed and later retrieved whenever called for. It is possible, and indeed common, to have a whole run consisting of a series of files to be included.

You can also replace variable items in the file with symbolic parameters, and to define the values these parameters are to have each time the file is retrieved.
