Here is a simple question : what is the maximum number of tasks that can be active at the same time ? I can't seem to find the anwser to this question anywhere. So I tried something. I was able to open 20 NEWCLI windows, every window has two tasks : - CON - Newcli I already had the following tasks : - RAM - File System - Trackdisk - input.device - CON So I had 20*2 + 5 = 45 tasks. Is 45 Tasks the maximum number of tasks ??? Marco Dedecker

Each shell/cli window and each RUNd program takes up a CLI. A CLI is a structure managed by DOS and not really part of a task or process. A process might *reference* a CLI structure but it isn't part of a process proper. There is NO maximum number of tasks or processes. System tasks do not run under a CLI and thus do not take from the CLI limit. Processes associated with DOS devices, tasks/processes associated with EXEC devices and libraries, tasks/processes created by user programs (not RUNd), and most resident programs are not connected to a CLI and thus do not take from the CLI limit. In fact, it should be noted that an EXEC task takes very little memory.... just the Task structure, stack, and (possibly shared) code. The only limit here is memory. -Matt

I remember seeing a program come through here that would allow more than 20 CLIs, for those that need many. MaxCLI, or some such name. -- Darren

It has nothing to do with the number of tasks that Exec allows you to create. To be specific, you can create 1 billion tasks, ((2^^32)/4), unless you run out of memory first. This limitation will be fixed in a future release. Valentin _________________________________________________________________________ The godess of democracy?

45 task?! you have a weird logic... Couldn't you run a program from the workbench when you had those 45 'tasks'? The limit is you memory size.... If you need to have 500 tasks no problems!

I have to say that you are not limited to 20 cli's.... There is a 'patch' called maxcli that will let you set the number cli you can open on a window.. I only check with 255 cli window, and I dont know if it's the limit or not...

I wish to thank everybody for replying to my question about the max. number of tasks. I didn't know that memory was the only limit for the number of tasks, and the stuff about the limit of 20 CLI's was new to me too. Thanks, Marco Dedecker
