John , " This talks about the _BPX_SHAREAS environment variable. This environment variable is not mentioned anywhere in the documentation of tcsh."� Your are right . BPX_SHAREAS cannot be used for tcsh . It is documented in USS planning guide . _BPX_SHAREAS Specifies whether the spawned child process is to be run in a separate address space from the login shell's address space or in the same address space. Use _BPX_SHAREAS is to improve performance in the z/OS� shell. The spawn callable service uses _BPX_SHAREAS when creating child processes. Is there anything distinctive about tcsh? Wouldn't the same apply to bash, or ksh, or dash, or any shell a customer cared to install? I suppose what distingishes tcsh is that z/OS elects to supply it as a base function. That ought to make tcsh responsible for being _BPX_SHAREAS-savvy. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
