Read the user guide. You can't use standard tcl commands (like if statements) or any interface tcl provides to NAMD (http://www.ks.uiuc.edu/Research/namd/2.13/ug/node9.html#SECTION00052200000000000000), but you can do things like ask for  minimization (http://www.ks.uiuc.edu/Research/namd/2.13/ug/node34.html -Josh
