The procedures for the WRITE function are
• SAR_OPEN_OUTPUT
• SAR_WRITE

The procedure declarations for SAR_OPEN_OUTPUT, SAR_WRITE,
SAR_WRITE_CONTROL, and SAR_CLOSE_OUTPUT are contained in the element
SAR$WRITE$DG in the SYSLIB file (SYS$LIB$*SYSLIB) or SYS$*RLIB$. This element is
obtained with the COPY statement. SAR$WRITE$DG contains all four procedure
declarations. All of the WRITE procedure modules are compiled with the G option using
the IBJ$ calling sequence.
