Is there a relatively simple procedure or command to return in bytes the amount of free memory(including chip and expansion)(basically something that returns the same number we see for free memory on the workbench screen.) if so, could you provide me with how to do that? This is needed for a program I am doing on SAS C so if the person has less than 10,000 bytes left, I can tell the user as such. thanx, Ross Goldberg

RTFM AvailMem( memory type) is a handy Exec.library function. bytes = AvailMem(MEMF_CHIP) Number of FAST mem bytes free bytes = AvailMem(MEMF_FAST) Number of FAST mem bytes free bytes = AvailMem(MEMF_CLEAR) Number of zero bytes free bytes = AvailMem(0) Total Number of bytes free

You can also combine tme all with the uninplemented MEMF_PUBLIC. One thing I always wondered about is what does AvailMem(MEMF_CLEAR) mean? ~CrisP. -- ------------------------------------------------- crisp@uk.ac.warwick.cs | estdwha@uk.ac.warwick.cu -------------------------------------------------

I believe MEMF_CLEAR is for use with AllocMem only (fills allocated memory with zeroes). Also, MEMF_LARGEST gives no meaning to AllocMem, just to AvailMem. |> ~CrisP. |> -- |> ------------------------------------------------- |> crisp@uk.ac.warwick.cs | estdwha@uk.ac.warwick.cu |> ------------------------------------------------- -- __ / |> Shorter of breath / \ __ __ / ___ _ _ |> and one day closer to death. / |/ / / / / /__/ / / / |> -Roger Waters, Time /____/ \_/|/\_/ /____\___/ / \__________ |> (Dark Side of The Moon) ______________/
