Perform an indexed iteration in a program.

Syntax:

for k=N1:N2:N3

…

end or

for k=N1:N2

…

end

where N1, N2, and N3 are numbers or simple expressions.

The syntax:

for k=N1:N2:N3

…

end

iterates k from N1 to N3 with a step of N2.

The syntax: for k=N1:N2

…

end

iterates k from N1 to N2 with a step of 1.

Notes:

1.If the iteration step is zero, the program is aborted with the error code

INFINITE_LOOP.

2.If N1, or N2, or N3 are variables, they are evaluated once before the iteration begins. If the variable changes within the "for" loop, the iteration process will not be affected.

3.Iteration variable k must be declared as a variable.

Example:

….	Start user program or function
float ra[20];	Float array declaration
int ia[20];	Integer array declaration
int k;	Variable declaration
…
for k=1:10	Start of iteration loop
ia[k]=100;	Update the first ten elements of the integer
	array
ra[k]=55.55;	Update the first ten elements of the real array
…
end	End of iteration loop
