Purpose
Function to update the value of an environment symbol
Syntax

See Also
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
Products
