>> But every variable is based on a pointer. A static variable is based on the pointer to static storage and a variable in a procedure is based on the pointer to the call stack entry of that procedure. That is irrelevant - it is still faster to calculate and store the required value once during initialization than calculate it every time it is needed at run time. The number of parms in an RPG program is finite and relatively small, so since there is a performance benefit from using a pre-initialized pointer at the cost of a (relatively) small amount of storage, so that is what the compiler used to do. >> is actually a relatively slow performer compared to pointer operations on other systems. Which is exactly why keeping one pointer per parm and loading it during the initialization phase is a good trade off! Barbara can tell us for sure, if this is true for RPG IV but I'd be surprised if it wasn't. Jon Paris Partner400 www.Partner400.com
