RE: *Blanks and *Blank

[Bob Crothers <bob@xxxxxxxxxxxxxx>]

There is a huge difference between what MOVE and MOVEA does.

MOVE treats the array element like a single field.  MOVEA ignores 
element boundaries.

In the example, MOVE will blank out the first element in the array but 
leave 2 thru 100 alone.

MOVEA will blank out all elements starting with the element 
specified...in this case, since you specified 1, the entire array.

And if you do a MOVE *BLANK ar1 where ar1 is an array and you did not 
specify an array element, it will also blank out the entire array.

The moral is unless you know you need to use MOVEA, you should 
probably do a MOVE or MOVEL.

And of course, there is no difference in the below between *BLANK and 
*BLANKS in the below....because there never (that I know of) is a 
difference between *BLANK and *BLANKS (besides the S)

Hans,

I think this two keywords may differ when using with array element(s) 
such
the following:-

A is an alpha array with a hundred elements, 1 byte each.

        MOVE            *BLANK  A,1
        MOVE            *BLANKS A,1
        MOVEA   *BLANK  A,1
        MOVEA   *BLANKS A,1

So, what is difference for these samples?
