Expressions for %%LDA - IBM i (AS/400) only

%LDA is a special variable that can be used to specify Local Data Areas for IBM i (AS/400) jobs.

The following format can be used when specifying an expression to assign a value to job submission variable %%LDA for a job:

%%LDA[_startpos[_length] [_dec]]=Variable_exp

• startpos: A number indicating the starting position in the LDA at which to place the results of the specified expression.
• length: A number, indicating how many positions in LDA to reserve for the results of the expression.
• dec: A number indicating how many decimal places to include in the packed decimal value passed to the LDA.
• Variable_exp: The Variable expression whose resolved value should be placed in the indicated location in the LDA.

EXAMPLE: Assuming that the system date is December 15, the following expression:

%%LDA_2_3=%%DAY

is submitted to IBM i (AS/400) as:

CHGDTAARA *LDA(2 3) VALUE(15)

The following expression inserts the packed value of 00123.40 into the LDA starting in position 11 for a decimal length of 7 (Actual Packed length of 4):

%%LDA_11_7_2=123.4
