Execute command.

The "execute" or "exec" command executes a program or a file if it is associated properly to an existing application. Execute command doesn't need any user intervention.

Syntax:

execute=what_to_execute, mode, context

What_to_execute is the name of an executable file, or a file that is associated to an application, a website, etc.
Mode defines if the execution will be performed ONCE or ALWAYS.
Context indicates if the execution will be for VIEWER, PRINT or BOTH.

Example:

{execute=http://www.rpvsoftware.com,once,viewer}

"Exec" executes the commands without any user intervention and may be indicated to perform determinated tasks.

Depending on the task that you need to perform, the option ONCE is the most recommended. For instance, if you specify "{exec=x.exe,always,viewer}", everytime that the page in which the "exec" command is is shown, "x.exe" will be executed. Same effect will take place if the "exec" command is in mode "always" and is into the [header] section.
