2.3.8 Remark statement and control commands
2. 3. 8. 1 REM
Format REMr
r .... Programmer's remark
Function REM is a non-executable statement which is specified in a program line to cause
the BASIC interpreter to ignore the remainder of that line . Since REM statements
are non-executable, they may _ b e included at any point in the program without
affecting the results of execution. REM statements are generally used to make a
program easier to read, or to add explanatory notes to a program.
Multiple statement program lines
When more than one statement is included on a sfugle program line, each statement must be
separated from the one preceding it by a colon (:). Operation of the BASIC interpreter is
generally the same in such cases as when the same statements are specified on different lines.
For example, the two programs below produce exactly the same result.
10
20
30
40
~ ~
· · F ·
10 A=5:8=8:C=A:tB:PRINT
c
C=A:tB
PRINT C
Note: Also note that program operation may differ when multiple statement lines are used as
shown below.
10 INPUT A
20 B
=
0
This -program displays 1 if the value entered at
30 I F 99 <A THEN 8= 1 line 10 is greater than or equal to 100, and 0
40 PR I N T B if the value entered is less than 100.
50 END
10 INPUT A:B=0: IF 99 < A THEN 8=1 :PRINT B
20 END
This program displays 1 if the value entered.is greater than or equal to 100, but nothing
at all if the value entered is less than 100. The reason for this is that statements follow-
ing THEN on line 10 are not executed if the IF condition is not satisfied.
