5-6-1 Input Command
•
Input Statement
An input command is used to input the data during program calculation.
An input statement is used to input data into a variable using the keys during program
execution or program execution stops (after display shows a "7 ").
Format: INPUT ["character string".J variable
[, "character string", variable]
(Items enclosed in brackets may be omitted.)
The "character string" may be omitted. However. if it is written. the characters enclosed
in quotation marks will be displayed preceeding the question mark. This can be used
as a message during input.
The variables following the INPUT statement can be numerical variables (A, B, etc.),
character variables (X$, Y$. etc.). or the exclusive character variable ($). These can be
written consecutively using a " ,".
Example:
I NPUT A
INPUT
"DATA=", A
After an INPUT statement a
"? "
will be displayed and the PC-4 enters an input await
condition. At this time, if data is input and the
III
Key is pressed, program execution
will proceed to the next process.
The input await condition will not be released even if the
rD
Key is pressed. Therefore,
when you want to stop a program in execution, press
~~
.
*
Data which can be input using an IN PUT statement include numerical values or the
results (answers) of numerical expression (for numerical variables) and character
strings (for character variables).
In the case of INPUT A
Numerical value ......
123111
---i>
A=
1
23
Result of a numerical expression ......
14D25111
~
A=350
In the case of INPUT B$
ABCIII- B$=ABC
Character string······
789111- B$=789
Furthermore, other numerical variables can also be used as input for numerical
variables.
In the case of INPUT A (make X ;; 987654)
Variable .. ·.. ·
