I came from an older version of AutoCAD LT.  In it you could mess with the STARTUP Command variable (System variable) to get the start up dialog box.  Draftsight has the variable and it is named LGCYSTARTUP.  When I look it up it says, 'Legacy. Provided to maintain integrity of application scripts.'  

What does this mean?  I have changed the value but nothing happens.  Is this what the 'Legacy' variables are supposed to do?  Are they there just so the scripts don't throw errors but they don't do anything else?
