Description
This instruction is used to declare an array.
The following must be declared:
the name of the array,
its guide word,
its length or its type (L for a DATE type field, T for a TIME type field, Z for a TIMESTAMP type field and * for pointer),
its number of decimals (not mandatory),
the numerical type (B for binary, I for integer, U for unsigned integer) (not mandatory),
the array dimension (the result of Dimension1 * Dimension2 must be less than or equal to 32767),
*NODEF, so that this definition is not generated in the 3GL.
Notes:
- If the variable is already declared with the same characteristics, it is not defined again.
- The declaration of the types DATE, TIME, TIMESTAMP, INTEGER, UNSIGNED INTEGER and POINTER, is only compatible with the RPG generator.
Example
DECLARE_ARRAY WARRAY;W_ARRAY 15;2 10
DECLARE_ARRAY WARRY2;W_ARRAY_2 5;0 10;15
*
J = 1
I = 0
DO_WHILE I < 10
I = I + 1
W_ARRAY(I) = W_ARRAY_2(I,J)
