Example 1: DISPLAY ARRAY using full list mode
Database table definition:
CREATE TABLE customer
(
id INTEGER NOT NULL PRIMARY KEY,
fname VARCHAR(50),
lname VARCHAR(50) NOT NULL
);
INSERT INTO customer VALUES ( 101, "John", "Calagan" );
INSERT INTO customer VALUES ( 102, "Mike", "Torn" );
INSERT INTO customer VALUES ( 103, "Omer", "Winston" );
The "shop.sch" schema file:
customer^id^258^4^1^
customer^fname^13^50^2^
customer^lname^269^50^3^
Form definition file
"custlist.per":
SCHEMA shop
