Syntax
INPUT [[inputPrompt$] ,variable]
Parameters
inputPrompt$ is a string expression,
variable is a numerical or string variable.
Description
Causes the program to wait for user input, reads data
entered on the keyboard into a variable and then contin-
ues the program run.
INPUT will first output the inputPrompt$ on the 4400
screen. Then it waits for the user’s input.
INPUT can read
data entered either into a numeric or a string variable.
The ‘signal’ for input finished is the CR symbol (achieved
by the user pushing the E
NTER key).
The symbols entered by the user will be stored in
vari-
able
and the program will continue.
Notes:
– External keyboard and the keys of the 4400 may be
used in parallel. This means that an entry on the
external keyboard may be confirmed by pushing the
4400’s E
NTER key.
–In case
variable has been defined as a numerical
variable and the user enters any other symbol than
numbers and the decimal point, this will lead to an
error. A simple trick to avoid that is to always read the
value entered as a string and later convert that string
into a numerical value:
INPUT "Please enter channel number:" _
, channelno$
channelno = VAL(channelno$)
– With the help of the INPUT command, you may also
read data from a file or the SCPI system.
Examples
INPUT "What’s your name? ", name$
INPUT
(The program waits until the user pushes the
Enter key.)
