How to Use Functions

I am attempting to truncate all characters following "--" in the %title% metadata of my music files. I found an example of a function to perform this:

$puts(spacer,$strchr(%title%,"--"))$trim($left(%title%,$sub($get(spacer),1)))

However, I have no idea how to use this function. In Masstagger, when trying to use these functions in its "Set value..." or "Replace value..." options, it treats them as a literal string. How and where are these functions used? TIA

- Select files - Properties - Right Click on Track Title - Automatically Fill... - put code in pattern
Edit: Hmm, disregard that, I thought it worked but it just changed it to filename  :-) I don't know then.
Edit2: You can set %title% as a source but it still does not work

In the file properties window, click the Tools button and choose Automatically fill values. Use %title% as Source and %title%-- as Pattern.
I'm late

If you for some reason prefer Masstagger, use Format value from other fields...
Destination field name: TITLE
Formatting pattern:
Code: [Select]
$puts(spacer,$strstr(%title%,--))$trim($left(%title%,$sub($get(spacer),1)))
Note omitting the double quotation marks and the use of $strstr instead of $strchr, more info in Title Formatting Reference String functions.

(But I would use @davideleo's suggestion.)

Excellent, thank you both! %title%-- did the trick. Very efficient code. So that I may better understand how this works, I was wondering if either of you could point me to where this syntax is explained? Now that I've cleared out all the old parts of my files' titles, I would like to rebuild them with %album% and %date%. Thanks again.
