Ing. T.R.M. Pluym,
I'm in the process of building a pre-processor for enhanced version of VFP - something along the lines of VFP++ (as C is to C++). I would be curious to learn what additional features of Clipper you feel are missing from VFP.
The more detail you can provide me the better. Your example for the AADD() function was great!
Thanks!
Malcolm

> Description
>
> AADD() is an array function that increases the actual length of the
> target array by one. The newly created array element is assigned the
> value specified by .
>
> AADD() is used to dynamically grow an array. It is useful for building
> dynamic lists or queues. A good example of this is the GetList array
> used by the GET system to hold Get objects. After a READ or CLEAR GETS,
> GetList becomes an empty array. Each time you execute an @...GET
> command, the GET system uses AADD() to add a new element to the end of
> the GetList array, and then assigns a new Get object to the new element.

> AADD() is similar to ASIZE() but only adds one element at a time;
> ASIZE() can grow or shrink an array to a specified size. AADD(),
> however, has the advantage that it can assign a value to the new
> element, while ASIZE() cannot. AADD() may also seem similar to AINS(),
> but they are different: AINS() moves elements within an array, but it
> does not change the array's length.

> Note: If is another array, the new element in the target
> array will contain a reference to the array specified by .

> þ These examples demonstrate the effects of multiple invocations

>
> aArray := {} // Result: aArray is an empty array
> AADD(aArray, 5) // Result: aArray is { 5 }
> AADD(aArray, 10) // Result: aArray is { 5, 10 }
> AADD(aArray, { 12, 10 }) // Result: aArray is
> // { 5, 10, { 12, 10 } }
