- This syntax improves the readability of your program, especially if you have nested For loops. You must specify the variable that appears in the corresponding For statement. The start , end , and step expressions can evaluate to any data type that widens to the type of counter .
NESTED LOOPS.
- A nested loop is a loop within a loop, an inner loop within the body of an outer one. ... Then the second pass of the outer loop triggers the inner loop again. This repeats until the outer loop finishes. Of course, a break within either the inner or outer loop would interrupt this process.
- If condition is True, all statements are executed until the Wend statement is encountered. Control then returns to the While statement and condition is again checked. If condition is still True, the process is repeated. If it is not True, execution resumes with the statement following the Wend statement
