Local Data Item Declaration

Local data items are data items (also known as variables) that are declared in the procedure division body.

Context

    Procedure Division
        DECLARE Statement
        PERFORM Statement
        TRY Statement

local-declaration

Example

       declare i1 as binary-long
       display i1 
         
       *>   Optionally, the variables can be initialised inline 
        declare c2 as condition-value = true
        display c2

        declare string-list2 as string occurs 3 = table of string("Bill", "Ben", "LittleWeed")   

      **************************************************************************
      * Iteration Variables
      **************************************************************************

      *>   A variable can be declared at the point of use in an iterator. 
      *>   In this case the scope of i will be until the end-perform. 
           perform varying i as binary-long from 1 by 1 until i > 10
               display i
           end-perform

      **************************************************************************
      * Exception Variables
      **************************************************************************
       
      *>   The example below shows that you can declare e at the point of use.
      *>   It is in scope until the end-try.
           try
               display "exception test"
           catch e as type Exception
               display e::Message
           end-try

Further Information

The scope of any inline local variable is from the point of declaration until the end of the innermost containing block, where paragraphs, sections and the whole method are considered to be blocks.
