Two small helper AppleScript functions for joining a list and splitting a string given delimiter. Sure, quite an easy task, but it involves setting a global delimiter. Bit like FS in shell. I hope this helps a few folks out there starting out with AppleScript.

```applescript to joinList(aList, delimiter) set retVal to “” set prevDelimiter to AppleScript’s text item delimiters set AppleScript’s text item delimiters to delimiter set retVal to aList as string set AppleScript’s text item delimiters to prevDelimiter return retVal end joinList

to splitString(aString, delimiter) set retVal to {} set prevDelimiter to AppleScript’s text item delimiters log delimiter set AppleScript’s text item delimiters to {delimiter} set retVal to every text item of aString set AppleScript’s text item delimiters to prevDelimiter return retVal end splitString

```

Here a few lines showing how to use them:

applescript set tmp to my splitString(oldAlias as text, ":") set imgTags to my joinList(kwList, ",")

Again, no comments! Enjoy!
