OpenEdge Development:<br />Progress 4GL Reference RANDOM function

Release 10.1A: OpenEdge Development:
Progress 4GL Reference

RANDOM function

Returns a random integer between two integers (inclusive).
Note: This function returns a number from a pseudorandom sequence of numbers rather than a truly random sequence.

The Alternate Random Number Generator (-rand) parameter determines whether the same sequence of random numbers is generated for each session. For information on this parameter, see OpenEdge Deployment: Startup Command and Parameter Reference .

Syntax
RANDOM ( low , high ) 
low
An integer expression that is the lower of the two expressions you are supplying to the RANDOM function.
high
An integer expression that is the higher of the two expressions you are supplying to the RANDOM function.
Example

Often when you set up a database for testing purposes, you want to generate many records without actually keying in data for each record. The r-random.p procedure generates 10 order records and a random number of order-lines for each order record.
r-random.p
DEFINE VARIABLE onum AS INTEGER.
DEFINE VARIABLE olnum AS INTEGER.

DO onum = 1 TO 10 TRANSACTION:
    CREATE order.
    order.order-num = onum.
    order.order-date = TODAY.
    DO olnum = 1 TO RANDOM(1,9):
        CREATE order-line.
        order-line.line-num = olnum.
        order-line.item-num = olnum.
    END.
END.
