Don't worry, the new LSVBITFD works exactly the same as the old one from the caller's point of view. Nothing is changed except that it must be called from EXEC2, REXX, XEDIT or from the keyboard (and can't be called from EXEC 1) and that there is a new and completely useless option, SKIP (don't produce any output). If "EXECIO * DISKR (FIND" on a 1740 * 8 chars file took less than 5 times the time a "LSVBITFD nodeid nodeid (SKIP" takes, I would not have implemented it. But alas, EXECIO is one of the finest IBM programs and I chose not to use it to determine whether a node is in the local routing tables or not. Eric
