Installation of this support is recommended prior to the installation of IX/370." And the next page says: "Applications and editors that interpret each character as it is entered on the user's terminal have the greatest impact on processor utilization and therefore should be used with discretion." So try not to move your cursor around too much. -- Neal Macklin (408) 737-5214 ...{hplabs,ihnp4}!amdahl!nzm10 [The opinions expressed are those of the author and not necessarily those of Amdahl Corporation, its management, or employees.]
