MvDIMENSION

---

If you think of a single dimension array as an simple numbered list, a two dimension array can be though of as a spreadsheet with numbered rows and columns. Miva Script provides flexible tools for creating even more complex data structures.

Miva Script arrays are fully multi-dimensional (up to the limits of the system). If a value is assigned to an index or member that did not previously exist, the entry will be created.

Syntax

<MvDIMENSION INDEX = "numberic: { expression } | literal"> 

Attributes

Attribute	Description
INDEX	Declares the index of the array in NAME that will receive the VALUE.

Only allowed between <MvASSIGNARRAY> and </MvASSIGNARRAY>.

Two Dimensional Array

A tabular representation of the array declared below could look like this:

	Column 1	Column 2
Row 1	100	200
Row 2	300	400

Example

Result: 300

<MvASSIGNARRAY NAME="l.coordinates" VALUE="{ 100 }">
    <MvDIMENSION INDEX="1">
    <MvDIMENSION INDEX="1">
</MvASSIGNARRAY>

<MvASSIGNARRAY NAME="l.coordinates" VALUE="{ 200 }">
    <MvDIMENSION INDEX="1">
    <MvDIMENSION INDEX="2">
</MvASSIGNARRAY>

<MvASSIGNARRAY NAME="l.coordinates" VALUE="{ 300 }">
    <MvDIMENSION INDEX="2">
    <MvDIMENSION INDEX="1">
</MvASSIGNARRAY>

<MvASSIGNARRAY NAME="l.coordinates" VALUE="{ 400 }">
    <MvDIMENSION INDEX="2">
    <MvDIMENSION INDEX="2">
</MvASSIGNARRAY>

<MvEVAL EXPR="{ l.coordinates[2][1] }"><br>
