static member SubroutineAsync : 
        credentialOptions : CredentialOptions * 
        subroutineName : string * 
        argsNumber : int * 
        arguments : string *

(* Defaults:
        let _customVars = defaultArg customVars ""
        let _receiveTimeout = defaultArg receiveTimeout 0
*)
-> Task<string>

Parameters

credentialOptions CredentialOptions: Object with data necessary to access the Linkar Server: Username, Password, EntryPoint, Language, FreeText.
subroutineName String: Name of BASIC subroutine to execute.
argsNumber Int32: Number of arguments
arguments String: The subroutine arguments list. Each argument is a substring separated with the ASCII char DC4 (20).
customVars String (Optional): Free text sent to the database allows management of additional behaviours in SUB.LK.MAIN.CONTROL.CUSTOM, which is called when this parameter is set.
receiveTimeout Int32 (Optional): Maximum time in seconds that the client will wait for a response from the server. Default = 0 to wait indefinitely.

Return Value

TaskString
The results of the operation.
