ArrayWrite question

[Darrel Taylor]

NO, that would give compile errors.
ARRAYREAD gets data from an array. So you can't have constants as parameters.

ARRAYWRITE puts data in an array.

Consider the following program ...

TestArray  VAR BYTE[26]
N VAR BYTE
N = 9

    ARRAYWRITE TestArray,["ABCDEFGHIJKLMNOPQRSTUVWXYZ"]
    HSEROUT ["Before-",STR TestArray\26,13,10]

    ARRAYWRITE TestArray,[STR TestArray\N,"12345678"]
    HSEROUT ["After -",STR TestArray\26,13,10]

The output would look like this, and the data can be moved by changing the value of N. ...

Before-ABCDEFGHIJKLMNOPQRSTUVWXYZ
After -ABCDEFGHI12345678RSTUVWXYZ

If the data is always going to be placed at the same location, you can do it this way...

TestArray  VAR BYTE[26]
StartPos   VAR TestArray[9]

    ARRAYWRITE TestArray,["ABCDEFGHIJKLMNOPQRSTUVWXYZ"]
    HSEROUT ["Before-",STR TestArray\26,13,10]

    ARRAYWRITE StartPos,["12345678"]
    HSEROUT ["After -",STR TestArray\26,13,10]

Resulting in the same thing ...

Before-ABCDEFGHIJKLMNOPQRSTUVWXYZ
After -ABCDEFGHI12345678RSTUVWXYZ

<hr>ADDED:
You can also do the fixed position data like this ...

TestArray  VAR BYTE[26]

    ARRAYWRITE TestArray,["ABCDEFGHIJKLMNOPQRSTUVWXYZ"]
    HSEROUT ["Before-",STR TestArray\26,13,10]

    ARRAYWRITE TestArray(9),["12345678"]
    HSEROUT ["After -",STR TestArray\26,13,10]

Unfortunately, you can not do it like this, which would be very handy...

TestArray  VAR BYTE[26]
N VAR BYTE
N = 9

    ARRAYWRITE TestArray,["ABCDEFGHIJKLMNOPQRSTUVWXYZ"]
    HSEROUT ["Before-",STR TestArray\26,13,10]

    ARRAYWRITE TestArray(N),["12345678"]
    HSEROUT ["After -",STR TestArray\26,13,10]
