Control Character Specifiers
A control character specifier specifies that one or more control
characters for carriage return, line feed, or form feed be printed or
suppressed. It consists of one symbol: #, +, -, @, or /.
Table 6-13 lists the control character specifiers, their positions in the
image
, (the item that is output) and their effect on the DISP USING or
PRINT USING statement.

Examples
10 A$="ABC"
20 DISP USING "3A"; A$
30 DISP USING "K"; "xyz"
40 DISP USING "#,3A"; A$ !Suppress carriage return & line feed
50 DISP USING "K"; "xyz"
60 DISP USING "-,3A"; A$ !Suppress carriage return only
70 DISP USING "K"; "xyz"

ABC
xyz
ABCxyz

The sequence:
100 DISP USING "+,3A"; A$
110 DISP USING "K"; "xyz"
