Suppose you don't remember everything perfectly, and you want to see how to properly use an IDL function or check exactly what it does. This is the command for you -- it uses IDL's function which to locate the .pro file that's relevant, and then lists that file for you to peruse.
IDL> man,'man'
; ; a little tool for looking at other idl programs ; the memory is the first to go... ; pro man,fname name = which(fname) spawn,"less -X " + name end
IDL> man,'seeall'
; seeall.pro 10-29-98 Eric Weeks ; ; see http://www.physics.emory.edu/~weeks/idl ; for more information and software updates pro seeall,tr,dot=dot,izz=izz,dr=dr,short=short ; currently works only for ubertracker data ; z sets the 4th graph to be tr(z,*) ; /dr to plot sqrt(dx*dx+dy*dy) instead of z-coord ; /short to show shortest first if (not keyword_set(izz)) then izz=2 len=lentrk(tr) on_error,1; return to $MAIN s=sort(len(0,*))... and so on.
