List Command (List) - Radio Shack TRS-80 PC-4 Owner's Manual

5-6-11 List Command
• LIST command
A LI ST command is used to display the program contents. It can be used in both the
"R UN" mode and the "WRT" mode.
Format: LIST [line number]
LIST A
(Item in brackets may be omitted)
(WRT mode)
When followed by a line number, the program will be displayed in sequence starting
from the designated line number of the currently designated program area. When no
line number is designated, display will be made from the beginning of the program.
In the case of "L1ST A", this is a command to display the programs in all program areas.
It displays program contents sequentially from P0 through PH. This command cannot be
used by writing it in a program.
When performed in the "R UN" mode, the program contents will be displayed
sequentially from the designated line. However, when performed in the "WRT" mode,
one line is displayed each time the
lEI
Key is pressed.
Example:
(RUN mode)
LIST. 10 A=0
20
INPUT

30
A=A+B
40
GOTO
20
,LIST 20Dl

III
20 INPUT B_
30 A=A+B_
40 GOTO 20_
Also, if performed in the "WRT" mode, program editing (refer to page 34) is possible.
