DATA
Format: Abbreviation: Screen Display:
DATA value dHJTHBa d V
[■ value, . . . , value]
The DATA statement holds information that will fill variables in a
READ statement. Any type of information can be stored here,
separated by commas. If a comma, space, or colon are to be used
as data, they must be enclosed in quote marks ("). Two commas
with nothing in between will be read as zero, or an empty string.
Note: the information in brackets is optional.
The line containing the DATA statement doesn't actually have to
be executed while RUNning the program, so most programmers
leave all the DATA statements at the end of the program, out of the
way.
EXAMPLE:
10 READ A : PRINT A
20 READ A, B, C : PRINT A; B; C
30 READ AS : PRINT A$
40 FOR L = 1 to 5 : READ A : PRINT A; : NEXT
50 READ AS, A, B, B$ : PRINT AS, A. B, BS
60 END : REM YOU NEVER ACTUALLY HAVE TO HIT THE
DATA STATEMENTS!
