According to help nlsur what you have typed below is not the proper
format of the command.
nlsur func_prog @ depvar_1 depvar_2 ... [varlist] [if] [in]
[weight] , nequations(#)
{parameters(namelist)|nparameters(#)} [options]
so you should list the depvars for the several (4?) equations, then
give a varlist of variables to be passed to the routine, then comma,
nequations() option. In what you have written below you have a ) where
you should not and are missing the comma. Also, either parameters() or
nparameters() MUST be given.
Look at the examples at the foot of the help file for the simpler
example of a function evaluator program, and make sure your command
follows the appropriate syntax.
