Data Members

This function reads formula, starting at position start, and looks for
variable string. It returns the index of the variable name occurrence if
found. It returns -1 if not. A variable name is considered to be any
alphanumeric expression that can also contain '_'.

This function replaces in formula all the occurences of variable with name
oldvar by expression contained in newvar. It returns the number of replaced
occurences.
