You can run a script via the command line with this syntax:   

"<Scripter path>" -x "filename.bas"

The –x means execute, and quotes are necessary around the file path to the Scripter.exe file and the BAS file.

For example:

“c:\program files\golden software\surfer 16\scripter\scripter.exe" -x "\program files\golden software\surfer 16\samples\scripts\BaseMap.bas"
