Process file/records until a specific total is reached.

Yes, and this works great....thanks for your assistance.

Furthermore, the business changed the requirement to "equal to BUT NOT exceeding the amount, e.g., $100". So, I changed the following code to achieve the desired result:

Code: Select all

END=(81,8,ZD,LE,&LIMIT),
 

However, it only contained one record, so I'll continue to tweak the code until I reach the desired results.

You're the best!

You can add extra output statements to print intermediate results, to help debugging your version of code.
This is a typical approach for any software engineer who tries to create his own code, not only copying existing code from others.

Like this sample

Code: Select all

Try to think about the logic of this code.
