ELB for ReportWriter user‑overloadable routines

WTSupported in traditional Synergy on Windows
WNSupported in Synergy .NET on Windows
USupported on UNIX
VSupported on OpenVMS

The RWUSRLIB environment variable specifies the ELB in which user‑overloadable subroutines and functions called by ReportWriter reside.


The full path and filename of the ELB or shared image in which the user‑overloadable routines reside.


On OpenVMS, ReportWriter calls OPENELB on the shared image that is specified with RWUSRLIB before attempting to call the routines.

If you are using the ReportWriter external subroutine interface, you can pass the ELB name as a parameter to %RW_INIT instead of specifying it with RWUSRLIB.

Setting location

The environment. On Windows, this environment variable can also be set in the [synergy], [dbr], or [myprog] section of synergy.ini (where myprog is any .dbr file).
