any subsequent LPRINT statements will be started on a new line
on the Atari 825 .
However, if an LPRINT statement prints 38 characters or l ess and
ends
with a comma, output from any subs equent LPRINT
statement will be begun on the same line at print position 41.
Printing also begins at this position, if LPRINT is used to print 40
characters or less and ends with a semicolon.
INPUT Statements
Data can be input into the computer wh ile a program is being
executed. This
is accomplished with the INPUT statement. For
example, when the following statement is executed,
100 INPUT A
the
computer will display a question mark and wait for the
operator to enter a response. That entry wil l be assigned to the
variable
A. The entry must be ended by pressing the Ent er key.
Program execution will then resume.
The values
of several numeric variables can be input with a single
INPUT statement as shown in the example below.
200 INPUT X, Y, Z
When the preceding INPUT statement is executed, the INPUT
prompt (?) will be displayed. The operator should then enter the
data items for X, Y, and Z. Each input should be separated by a
comma. The Return key should be pressed after
all input entries
have been made. An example
of a valid entry for the preceding
INPUT statement is given below .
100 , 200, 300 I
The INPUT statement in Atari BASIC functions somewhat
differently with string inputs than with numeric inputs.
First
of all, the st ring variable used with INPUT must have been
dimensioned earlier in the program.
