save {equations|variables|all} to <file>

- Save the current state to a file.

The "save" command is used to write a snapshot of all or part of the current problem state to a specified "file".

One of the following keywords must be used to determine what will be saved:

equations - Save only the set of stored equations.

variables - Save only the set of evaluated variables and locks.

all - Save all stored equations, evaluated variables, and locks.

A save file can be "load"ed back into the program to restore the saved data.

e.g. save equations to test.eqn

save all to problem.tmp
