The sybprocsdev devices stores the sybsystemprocs database, which contains most of the Sybase-supplied system procedures. System procedures are a collection of SQL statements and flow-of-control statements that perform system tasks, for example, sp_configure.
The system procedures that are needed during recovery situations are stored in the master database.
sysprocsdev is the default system name for this device. However, it is frequently referred to as the sybsystemprocs device, since it stores the sybsystemprocs database.
