Yes you can effectively. Write one Phantom routine that selects these files, one by one and loops through every record just reading it then moving on. This will smoothly keep the records in memory even if your actual user-accessing of them is chunky. And yes you can create your own internal hashtable. Just DIM an array to the modulo you want and then apply the standard routine to determine which cell your id goes to and put it there or get it from there.

RE: [UV] Memory resident hash tables/files
Marco Try a RAMdisk - works a treat. If you are sure you *need* internal hashtables in memory you can use them via the GCI interface by cutting your own C code around the C++ functions you mentioned. I would be very cautious about needing these - if they are relatively small they are likely to be memory cachedlittle benefit Take a GOOD look at the rest of your system first - it's surprising what you can find ;-) Regards JayJay -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Marco Manyevere Sent: 23 March 2004 07:06 To: [EMAIL PROTECTED] Subject: [UV] Memory resident hash tables/files Hi All, I would like to store records from small static parameter files that are accessed frequently in a memory resident hash table in the common area.
