55. Tab command
    ~~~~~~~~~~~
When you are using the simple TAB(X) command, you will find that items
already printed to the left are liable to be blanked out. This is a mixed
blessing, and can be avoided by using the full TAB(X,Y) syntax. However, this
can be inconvenient at times, but you will find that using TAB(X,VPOS) can be
used instead in most cases. Try using TAB(20,VPOS) instead of TAB(20) in the
example.

 10 PRINT"HELLO":pause=INKEY(200):VDU11
 20 PRINT TAB(20)"THERE"
