Initialization and Termination Routines
SICOMM
Function Initialize the ZPI/O environment
This subroutine initializes system-wide common blocks. SICOMM or SIISIL
(page 41 – a replacement subroutine for SICOMM) must be the first
subroutine called when using the Z-MAP Plus I/O Access Library.
SICOMM sets all output print units to the standard default, usually unit 6. For
more control on where messages are printed, see SIISIL (page 41).
Environment The application program must contain the declaration:
COMMON/WRKSPC/IWORK(N)
where N is normally greater than 10,000. A typical value for N is
100,000. However, N must be equal to LTHWRK.
Call this routine (or SIISIL) first and only once in all application
programs.
