You can use gp to change the values of parameters one by one, as prompted by the program. The current values and initial guesses (as compiled into your C-module) are printed for each.

Before being prompted for new values, you are asked if you wish to restore either the compiled-in initial values or the previous values, that is, the values used before the last attempt at fitting with the fi command.
