More than two items may be d isplayed on the same line through a variation of the PRINT

Shakespeare it ain't, but it does illustrate the action of the PRI NT statement when the printable
items are separated by semicolons. In this format, the items are adjacently displayed with a
minimum separation between them. This capabili ty is very handy for creating "natural" looking
output (i.e. output which flows together>.
!!Qrr:
If the length of the informat ion displayed exceeds the sPace available on the disPlay
(25 characters), the- items at the end of the print list will not be seen.
Another use of the hard.working semicolon is at the very end of a PRINT sta tement. In th is
capacity, the semicolon indicates that the output currently on the display should be saved and
that any new outp ut (from the next P RINT uatemcnt) should join the old output on the same
line. This process is easier to program than to describe, so lot's experiment with the followi n9
program (don't fo rget the NEW command) :
Program listing:
100 PRINT " HUMPTY ";
1 10 PRINT " DUMPTY "
