Description
The SET RUNCLEAR command controls whether the screen is automatically cleared, before and after execution of an Operating System command via the RUN / ! / !! Commands or the RUN() function.
With SET RUNCLEAR ON, the screen is automatically cleared, and when SET RUNCLEAR is OFF, the display is retained. This latter setting allows for more efficient execution of operating system commands that do not require any screen output. By default SET RUNCLEAR is ON.
This command allows the optional logical expression <expL> to be evaluated. If a value of .T. is returned, RUNCLEAR is set ON, otherwise it is set OFF.
Example
set runclear off run sysbackup > /dev/null 2>/dev/null set runclear on
Products
Recital
