Operating system script execution

Some systems, which use Linux operating system, can execute generic OS scripts, recalled from screen pages, in order to execute external programs.The call takes place by setting 2 system variables:@@EXECSCRIPT: string which contains the program to execute@@EXEC: counter to increment when the script execution needs to take place.Example:strcpy(@@EXECSCRIPT, ‘/ata0a/gefran/pag_script/start_pdfviewer.sh “/ata0a/eView.pdf”‘)@@EXEC := @@EXEC+1;The file/URL parameter must be inserted between “” because external scripts arguments are divided by spaces (e.g.: arg1 arg2), and with “” it’s possible to group them as a single argument.
