Description

The GETENV() function returns the value of the environment variable <expC>. Its main purpose is to pass information into Recital (e.g. from DCL command procedures, or UNIX/Linux shell scripts). In UNIX, Linux and Windows it returns the value of an environment variable. In OpenVMS, it returns the value of a DCL symbol. When used in conjunction with the PUTENV() function, the GETENV() function is very useful for passing parameters to Recital programs spawned in the background.

Example

? getenv("file")
/usr/recital/patrons.dbf
