PUTENV()

PUTENV()

Class

Environment

Purpose

Function to update the value of an environment symbol

Syntax

PUTENV(<expC1>,<expC2>)

See Also

GETENV()

Description

The PUTENV() function updates the value of <expC1> with the character expression <expC2>. The value of the symbol can be retrieved using the GETENV() function. If variable <expC1> does not exist, it is created. If the operation is successful, then PUTENV() returns .T., otherwise .F.. The PUTENV() function is very useful for passing parameters to Recital programs spawned in the background, when used in conjunction with the GETENV() function.

Example

set printer to spooler
putenv("db_print","/usr/recital/UD/print_labels")
list status to print
? getenv("db_print")
/usr/recital/UD/print_labels
