{ copy Files With certain extentions to a specific directory (Both
 parameters specified at the command line or in a Text File).. I cannot
 seem to find a command withing TP 6.0 to copy Files.. I have looked
 several times through the manuals but still no luck.. I even asked the
 teacher in Charge and he did not even know! Ok all you Programmers out
 there.. Show your stuff.. If you Really want to be kind, help me out
 on this..I am just starting in TP and this is all new to me!
