About this Playground

The Harbour Playground is a web service that runs on os.allcom.pl's servers. The service receives a Harbour program, compiles, links, and runs the program inside a sandbox, then returns the output.

There are limitations to the programs that can be run in the playground:

• The playground can use most of the standard library, with some exceptions. The only communication a playground program has to the outside world is by writing to standard output and standard error.
• In the playground the time begins at 1999-05-04 14:32:22 UTC (determining the significance of this date is an exercise for the reader). This makes it easier to cache programs by giving them deterministic output.
• There are also limits on execution time and on CPU and memory usage.

By default the playground uses the latest 3.2 snapshot of Harbour.
