The VMAKE initialization process is based on environment variables.
In Windows NT, environment variables must be encapsulated in percentage symbols.
On UNIX systems, environment variables are prefixed with a $. This is also the selected notation in this documentation.
All of the environment variables listed here, with the exception of $NOQUIET, can be set with the
initDev_SAPDB.bat (Windows NT) or initDev_SAPDB (UNIX) initialization script. This script is stored in the SAPDB_DEV directory when the development environment is installed.
