Error 19: The step of this FOR loop must be constant

Reason

This code line uses a loop statement (FOR). The STEP of this loop statement is likely to change at each iteration.

Remark: Only the loops based on a local variable (integer or real) accept a variable step.

Correction

Modify the STEP of your loop statement.

Example

Using a loop statement with a variable step to initialize an array

Code triggering the error

J is int = 0
I is int = 0
MyArray is array of 5 int
FOR I = 1 TO 5 STEP J+1
MyArray[I] = I
END

Possible correction

Use a fixed step.

J is int = 0
I is int = 0
MyArray is array of 5 int
FOR I = 1 TO 5 STEP J
MyArray[I] = I
END
