From: Gary Guthrie <garyguthrie@charter.net> > You guys ARE kidding, right? well, it is the same number of bytes to be read, so if the O/S handles caching correctly it shouldn't matter (as the time to make 100 calls vs. one call can be neglected). But the original question was a bit silly (sorry sas). Without information about record sizes, field sizes, how many times the program will be run, etc., no reasonable answer can be given. hence my answer: try it in your environment and with your data and see.
