Hi Jeff,
You could make it an object with the functions defined as methods and call it something like myUtilities.
DEF CLASS "myUtilities"
FUNCTION pair$(key$, value$)pair
END DEF
pair:
ENTER key$, value$
...
return result$
Then in programs you want to use it you do a myUtilies=NEW("myUtilties"). Then you simply call the functions like myUtilities'pair$("Key","Value")
