Real number in DLV memory

[Henryp]

How do I show a real number using the DMD data view when the value is held in a DLV memory address? The drop down box doesn't support this as an option.

Since Do-more is strongly typed, the element now dictates the "native" format.  As you know, DLV is unsigned 16 bit word.

To address issues like this, Do-more supports a concept of "casting" the element, to change the instruction or Data View's perception of the data type.

Use ":R" as a suffix on a data-block element to "cast" it to a REAL.  Note that for a REAL cast, the element MUST be DWORD-aligned, so DLV0, DLV2, DLV4 can be cast to a REAL by using DLV0:R, DLV2:R, DLV4:R.  Hence, you can not cast DLV1 as a REAL.

However, you can use PUBLISH and SUBSCRIB instructions to copy mis-aligned memory into other strongly typed memory and vice versa.

For more details on Casting, look at Do-more Designer Help Topic DMD0309.
