Rahul Mangaldas Box 1311 Clark University Worcester, MA01610-1477 BITNet: rmangaldas@clarku.bitnet -------------------------------- I am setting up a mailbox channel on a device using LIB$ASN_WTH_MBX, which creates a mailbox for the specified device and returns the created mailbox's channel number. My question is: How do you write to this mailbox? I want to set up a mailbox for a spawned process to send it DCL commands from a Pascal or C program, but can't find any LIB$ routines to do that. (I presume one cannot treat a mailbox like a file and use <write()> or <fprintf()> to write to it.) Thank you for your help. Rahul Mangaldas.

Just use the SYS$QIO system service with a function code of IO$_WRITEVBLK. For more information, check the I/O User's Reference Manual, Chapter 7. Jim
