That depends on the program, the exact form of the functions, how general you want it to be, etc. etc. One possibility is to have it all in one string and start parsing on the brackets, you would need a way of distinguishing between brackets that are part of the equation and brackets that are deliminating different equations, but with some careful thought that can be done. Alternatively you can let each equation be an option. This can be especially attractive if there is a known (maximum) number of equations. You can always take a look inside other programs that allow multiple equations, and see how they handle those: e.g. -heckman- could be an example where the different equations are handled through an option and a regular varlist or -sureg- is an example where the equations are deliminated with brackets. To look inside programs you can use -viewsource-. Hope this helps, Maarten --------------------------------- Maarten L.
