I guess something like this: char elem(unsigned index){ static unsigned long oldblock; static int been_here = 0; static char buff[BUFLEN]; long block; block = index/BUFLEN; if(!been_here || block != oldblock){ been_here = 1; Read_Block( oldblock=block ); } return buff[ index % BUFLEN]; } Ciao Tom ************************************************************* * Thomas Demmer * * Lehrstuhl fuer Stroemungsmechanik * * Ruhr-Uni-Bochum * * Universitaetsstr. 150 * * D-44780 Bochum * * Tel: +49 234 700 6434 * * Fax: +49 234 709 4162 * * http://www.lstm.ruhr-uni-bochum.de/~demmer * *************************************************************
