Directory Program Fast I/O Support This support enhances the performance of the directory program (DeKDIR) when run under eMS by using blocking factors during reading and writing
of the directory source copy. Without one SO-byte source
record is read at a tiae resulting in time and resource inefficiency. Thrau, h blocking, the amount of I/O required to process the complete file las been reduced, thereby yielding both processor and elapsed time savinss.

Support for the MSGNOH (Message No Header)
Command (CP) VM/370 now allows a service virtual aachine with privilege class B to
send unformatted .essages to other users of the systea. CP neither
prefixes these unforaatted aessages with the standard aessager beader (time stamp plus source identifier) nor inserts blank lines between
consecutive lines of output. The result is a more efficient method of
co •• unication between a VM/370 user and a V8/370 service virtual machine.
