User created script functions with arguments

You can create script functions that need arguments in the input. In the script function, you use #1 to retrieve the first argument in the input, #2 to retrieve the second argument, and so on.

You can also declare arguments to a function as local variable names. See Using local variable names as arguments to a function.

Example 34

Function with two input arguments

Function

func FileNameString ()
{
    $namestring = #1 + "_" + #2;
    return $namestring;
}

In this example, the script function FileNameString uses two input arguments to create the string “customer name_invoice number”.

Function call

$nameAndNumber = FileNameString (&yourReference, &invoiceNumber);

Result

If &yourReference is Mike Jones, and &invoiceNumber is 1020, the value of $nameAndNumber is “Mike Jones_1020”.

 

Example 35

Function with substrings

Function

func ChangeDateFormat ()
{
    $month = #1(1,2);  //Character 1 and 2 in input string
    $day = #1(4,2);    //Character 4 and 5 in input string
    $year = #1(7,4);   //Character 7 to 10 in input string
    $newformat = $year + "-" + $month + "-" + $day; 
    return $newformat;
}

In this example, the script function ChangeDateFormat changes the date format mm/dd/yyyy to yyyy-mm-dd.

Function call

$dateFormatSWE = ChangeDateFormat (&invoiceDate);

Result

If &invoiceDate is 05/21/2008, the value of $dateFormatSWE is 2008-05-21.
