Command Line Handling Settings for Service Interfaces

Return trigger executable name as argument zero: Select this to specify that argument 0 of a command line (for example, in ACCEPT ... FROM ARGUMENT VALUE statements) is considered to be the program name. If you don't select this, argument 0 is considered to be the first command-line parameter.
Equivalent tunable: arguments_are_initial
Return command line to first ANSI ACCEPT or READ STDIN: Select this to return the command-line used to start your application in the first ACCEPT statement. If you don't select this, the first ACCEPT statement behaves like all others and takes input from the user. This is the ANSI-compliant behavior.
Equivalent tunable: command_line_accept
