Hi,
I have create a little program with exercises for childeren.
I have a table with the exercises.
I want each time I start the program re-order the complete table in an new random order. How can I do this?
Thanks,
Marc
Marc,
FW has a function nRandom(nRange) which you could use.
The issue is that you want a list of random numbers and you don't want any of them repeated. So, I would use an array and use DO WHILE to keep adding random numbers until the array is full. Each time you generate a new number you have to check the array to see if the number already exists. If so, then generate a new number. If not, then add the number.

James,
Thanks for pointing me to the direction. I'm gona add a field in the database,and fill it with a random-number generated with nRandom().
Then I will index the database on that field.

Marc,
Well, that should work, but it would be faster to generate an array and use the numbers in the array as recno's. This method would not require any disk writes or indexes.
