Radio Shack TRS-80 PC-3

when you press (ENTER) at the end of a calculation, the contents of the display will be printed on one line and the results will be
printed on the next. For example:
Input
3@@ / 5@
Paper
300/50
6.
You may print output on the Printer from within BASIC programs by using the LPRINT statement (see Chapter 8 for details).
LPR INT functions in exactly the same fashion as the PR INT statement, since both the display and the Printer are 24 characters
wide. The only difference is that, if you PR INT something to the display which is longer than 24 characters, there is no way for
you to see the extra characters. With the LPRINT verb, the extra characters will be printed on a second and possibly a third line,
as
is required.
Programs which have been written with PRINT can be converted to work with the Printer by including a PRINT=LPRINTstate-
ment in the program (see Chapter 8 for details!. ALL PRINT statements following this statement will act as if they were LPRINT
statements. PRINT=PRINT will reset this condition to its normal state. This structure may also be included in a program in an
IF
statement allowing a choice of output at the time the program is used (see Relationship of Two Variables example in Chapter 9).
You may also list your programs on the Printer with the LUST command (see Chapter 8 for details). If used without line numbers,
LUST will list all program lines currently in memory in their numerical order by line number. A line number range may also be
given
with LUST to limit the lines which will be printed. When program lines are longer than 24 characters, two or more lines
may be used to print one program line. The second and succeeding lines will be indented four characters so that the line number
will clearly identify each separate program line.
