I have a variable declared in a existing program as mentione below:

DCL A(1:4) DEC FIXED(10);

Can any one help me in understanding what does A(1:4) actually mean... ?

Thanks.

Hi,

DCL A(1:4) DEC FIXED(10);

It is single dimentional array where it can have 4 rows and 1 column.

for A(1:4), 1 represents the lower bound and 4 represents the upper bound of A.

Here is another example

DCL A(1:4, 1:4) DEC FIXED(10); is a two dimetional array where a can have 1 to 4 rows and 1 to 4 columns like 4 X 4 matrix.
