CHAPTER 6 Command Reference
Explanation:
1) Repeats process contained between FOR and NEXT statements a number of
times specified by the control variable. The value of this variable is changed,
from the initial to the final one, by the increment for each repetition of the
process. When the value of the control variable exceeds the final value, repeti-
tion is terminated.
2) When the initial value is larger than the final value , the execution between
FOR~
NEXT is performed only once.
3) When the increment is positive , the value of the control variable increases by
each increment. When the increment is 0, execution will be repeated end-
lessly. When the increment is negative, the value of the control variable
decreases by each increment. If increment is omitted, one will be specified.
4) A NEXT statement must always correspond to a FOR statement and must be
written after it.
5)
FOR~
NEXT loops can have the following nested structure.
10 FOR I= 1 TO 1 0
TI
20 FOR J=11 TO 20]
30 PR INT I ; " : '' ;
J
40
NEXT

END
6) Nesting can be performed with up to 4 levels.
7) When a FOR
~
NEXT loop is terminated, the value of the control variable
exceeds the final value by the value of the increment.
8) A branching out of a FOR
~
NEXT loop can be performed.
If branching
inside a FOR
~
NEXT loop by an IF statement or GOTO statement is
attempted, an error occurs.
