The array definition function is used to define the occurrences and layout of an array (X-arrays are not supported).
Array definition is initiated by the field command
.A or by issuing the line command
..E and then marking the required field with the
function code A.
The table definition function is used to define the occurrences and layout of more than one array at the same time. The arrays must begin in the same map line.
Table definition is invoked by the line command
..A.
This section contains information on the following:
The upper portion of the following screen is displayed for the purpose of array definition:

You can specify the following:
A one-dimensional array consisting of 10 vertical occurrences with 2 blank lines to be inserted between neighboring occurrences.
Name #001 Top Dim 10_________ 1__________ 1__________ ------------------------------------------------------------------------------- Dimensions Occurrences Starting from Spacing 1 . Index vertical 10_ ________ 2 Lines 0 . Index horizontal 1__ ________ 1 Columns 0 . Index (h/v) V 1__ ________ 0 Cls/Ls |
Same as Example 1 except that the array is to be horizontal.
Name #001 Top Dim 10_________ 1__________ 1__________ ------------------------------------------------------------------------------- Dimensions Occurrences Starting from Spacing 0 . Index vertical 1__ ________ 0 Lines 1 . Index horizontal 10_ ________ 1 Columns 0 . Index (h/v) V 1__ ________ 0 Cls/Ls |
A two-dimensional array. The first dimension consists of 10 vertical occurrences with 1 blank line between neighboring occurrences. The second dimension consists of 5 horizontal occurrences with 2 blank columns between neighboring occurrences.
Name #001 Top Dim 10_________ 5__________ 1__________ ------------------------------------------------------------------------------- Dimensions Occurrences Starting from Spacing 1 . Index vertical 10_ ________ 1 Lines 2 . Index horizontal 5__ ________ 2 Columns 0 . Index (h/v) V 1__ ________ 0 Cls/Ls |
Same as Example 3 except that the order of the dimensions is reversed.
Name #001 Top Dim 5_________ 10__________ 1__________ ------------------------------------------------------------------------------- Dimensions Occurrences Starting from Spacing 2 . Index vertical 10_ ________ 1 Lines 1 . Index horizontal 5__ ________ 2 Columns 0 . Index (h/v) V 1__ ________ 0 Cls/Ls |
A three-dimensional array. The first dimension consists of 3 vertical occurrences with 1 blank line between neighboring occurrences. The second dimension consists of 5 horizontal occurrences with 2 blank columns between neighboring occurrences. The third dimension consists of 2 occurrences, expanded vertically within each occurrence of the first dimension.
Name #001 Top Dim 3__________ 5__________ 2__________ ------------------------------------------------------------------------------- Dimensions Occurrences Starting from Spacing 1 . Index vertical 3__ ________ 1 Lines 2 . Index horizontal 5__ ________ 2 Columns 3 . Index (h/v) V 2__ ________ 0 Cls/Ls |
An example of using Starting from. The first
dimension consists of 10 vertical occurrences starting from index
I. I is defined in the map editor with Natural data
format/length N7 by default. The second dimension consists of 5 horizontal
occurrences starting from the index 3.
Name #001 Top Dim 10_________ 5__________ 1__________ ------------------------------------------------------------------------------- Dimensions Occurrences Starting from Spacing 1 . Index vertical 10_ I_______ 1 Lines 2 . Index horizontal 5__ 3_______ 2 Columns 0 . Index (h/v) V 1__ ________ 0 Cls/Ls |
An example of making a two-dimensional display from a one-dimensional array. The array consists of 40 elements. It is displayed in two columns with 20 lines each. This is achieved by specifying 0 as the horizontal index.
Name #001 Top Dim 40_________ 1__________ 1__________ ------------------------------------------------------------------------------- Dimensions Occurrences Starting from Spacing 1 . Index vertical 20_ ________ 0 Lines 0 . Index horizontal 2__ ________ 10 Columns 0 . Index (h/v) V 1__ ________ 0 Cls/Ls |
A table of one or more arrays which all begin in the same map line is
defined with the ..A line command. When you enter
the ..A line command, the following screen is
invoked:

Note:
When applying the ..A command to arrays
which were not defined by an ..A command but by an
.A command, may result in a modification or even a
destruction of these arrays.
The example screen above contains the following fields:
| Field | Explanation |
|---|---|
| Main Index | The number of vertical occurrences, the starting position and the number of lines to be skipped between dimension occurrences. |
| Second Index | The direction (horizontal or vertical), the starting position
and the number of lines/columns to be skipped between dimension occurrences.
The second dimension only applies if one of the arrays has more than one dimension. In this case the second dimension can be displayed either horizontally (in which case there must be enough space in the line for all selected occurrences) or vertically (in which case there must be enough lines on the map to display main dimension times second dimension occurrences, including line spacing). |
| Third Index | The direction (horizontal or vertical), the starting position
and the number of lines/columns to be skipped between dimension occurrences.
The third dimension only applies if one of the arrays has more than two dimensions. In this case the third dimension can be displayed either horizontally (in which case there must be enough space in the line for all selected occurrences) or vertically (in which case there must be enough lines on the map to display main dimension times second dimension times third dimension occurrences, including line spacing). |
| Name of Variable | All names of field arrays contained in the table are displayed. |
| Col Pos | The column position in which the field is located. This is displayed for informational purposes only. |
| Dimension Size | The upper bounds Ind1,
Ind2 and Ind3 of an array.
The dimensions of the array defined in the map must not exceed the dimensions of the corresponding array defined in the Natural object that invokes the map. |
| Order | The order in which the dimensions are to be defined: M, S and T correspond to Main, Second and Third. |
| 2. Occ. | The number of occurrences to be defined for the second index. |
| 3. Occ. | The number of occurrences to be defined for the third index. |
This is an example of defining map fields that correspond to the following program definition:

ARRAY1 is a one-dimensional array with ten occurrences.
The first two occurrences are expanded in the table.
ARRAY2 is a two-dimensional array. The first index
consists of ten occurrences and the second index consists of two occurrences.
The first two occurrences of the first index and both occurrences of the second
index are expanded in the table.
ARRAY3 is a three-dimensional array. The first index
consists of ten occurrences, the second index consists of two occurrences and
the third index consists of three occurrences. The first two occurrences of the
first index, both occurrences of the second index and all three occurrences of
the third index are expanded in the table.
The table is defined as a collection of arrays which share the following characteristics:
The number of occurrences of the main index must be the same for each array of the table. The main index is always expanded vertically.
All elements of a specific index must be placed in the same line. Thus, spacing between the elements of a specific index depends on the array with the largest dimension.
