It's the result of another function. That detail is below, but it's in full context in my first post in the thread.

 Code:
$Mappings = EnumIni('.\netprint.ini', 'MAPPINGS')

;;FUNCTION       EnumIni() 
;; 
;;ACTION         Enumerates sections or keys of an INI file 
;; 
;;AUTHOR         Glenn Barnas  
;; 
;;VERSION        2.0

;;DATE MODIFIED  2004/10/16 
;; 
;;SYNTAX         EnumIni(File [, Section]) 
;; 
;;PARAMETERS     File - 	REQUIRED, path/name of INI file to examine 
;; 
;;               Section -	OPTIONAL, Section name to parse 
;; 
;;REMARKS        Returns an array containing the sections in an INI file, or 
;;               an array of key names in a specified section. Errors are returned 
;;               for non-existant files or INI file reads. If the specified file 
;;               contains no sections, or the specified section contains no keys, 
;;               the UDF exits with error 13 and returns a null array. Thus, a For-Each loop 
;;               will properly perform no iterations if no data is returned. 
;; 
;;               CAUTION - Error 13 is returned for empty files, or nonexistant sections. 
;;                         This is not necessarily a "failure". 
;; 
;;RETURNS        Array of sections or keys in a section 
;; 
;;DEPENDENCIES   none

;;TESTED WITH    Kix 4.2+, NT4, W2K, WXP, W2K3

;;EXAMPLES       $Sections = EnumIni('.\config.ini')
