INPUT (I.)
The INPUT statement causes data to be assigned to variables.
CONFIGURATION
INPUT [#a,] x~ [~$J ..
The INPUT statement is generally used with the keyboard,
editor, disk, or Program Recorder. The INPUT statement
requires an I/ O channel number as well as a previous OPEN
statement if any device other than the editor is used.
The
correct format for numeric data is standard notation or
scientific notation. Spaces can appear before or after a numeric
value, but spaces within a numeric value cause an error. Numeric
data can be entered on the same line , separated by commas.
EXAMPLES
54, 4E5, -10
-3.45E-10
0,1,1 ,5,3,10
Expressions cannot be used as numeric data with INPUT. Any
format other than standard floating point decimal or scientific
notation causes an error.
Each line of numeric data must be followed by an end-of-line
character (RETURN).
String data
must also be followed by an end-of-line character.
Only one string data item can occur on a line . Also, a string data
can
be read only into dimensioned string variables. If the length
of a data item is more than the dimensioned length of the
variable, the excess characters are eliminated, but no error
occurs. Any character can be a part of a string data item for
INPUT (including commas and special graphics characters).
