Syntax Of Arrays In Microsoft Dynamics

Synatax

An array have to define in the following format of syntax only in the Navision (Microsoft Dynamics NAV) C/AL.

Identifier  [Index Expression1] , [Index Expression 2] , etc .

The 'Identifier' is the Variable identification of an array and this need to include any types of arrays. Only the difference occur in the 'Index Expression' area only. ie, If we need Single dimension array then we need only Index Expression1.  In that case following will be the sysntax

Identifier  [Index Expression1]

Exapmple : A[3]

In the case of Two dimensional  array we have to mension upto Index Expression2. 

And in the case of Three Dimensional Arrays we have to mension Index Expression1, Index Expression2, Index Expression3.

How to assingn values to the Arrays?

To assign values to the array element 4 as 50 then you have to mension in the following format.

A[4] := 50;

Diffrent Terms of Arrays

Index

Index is used to refer to single element in an array

Element

An element is a single variable in an array.

To access the 5 element in the array of QuantityArray, you have to specify like

QuantityArray[5]

Dimension

An array can be specified in different dimensions. In the abow example QuantityArray[5] is a type of one dimensional array. Array dimension can be one or more. But one dimension arrays more simpler than multidimension arrays. For specifying the Complex datas we are using Muli dimensional arrays.
