How to initialize a variable which is a constant in a LDA. Suppose I want to declare a variable #a N1(1:7) having constant values as 1,2,3,4,5,6, and 7 for respective occurance then how can we do that?

In data area editor screen, define the variable #a with

Format "N" and length 1. Then edit this variable/ field by

typing in a ".e" just before the level number of this

variable. This will take you the "Extended Field Definition

Editing screen". Type the code as "A" for Array index

definition. On the "Index definition" screen, declare your

index as 1:7 press enter and exit the screens until you are

back onto the data area editor screen.Now again type in

a ".e" to edit the same field/ variable and type code "S"

for defining the single initial values. On this initial

value screen, change the "Define as Constant" field value

from "N" (No) to "Y" (yes)and just below it define constant

values against each index value ranging from 1 to 7.
