&
A string if the left operand is a
string; a record if the left
operand is a record; a list if
the left operand is another value type
The
concatenation operator can be used to combine two values to produce a
single third value combining the operator’s two
operands. You will mostly use this operator for
string concatenation. However, it is also often
used to add to records or lists. Make sure not to confuse this
operator with the + symbol, which is the
concatenation operator of Java and JavaScript that is only used for
addition and scientific notation (e.g., 1.2e+6) in AppleScript.
"My age is dare I say " & 43 (* combining a string and a number returns a
string as in "My age is dare I say 43" *)
{"apples","oranges"} & {"bananas"} (*combine two lists to make one list:
{"apples","oranges","bananas"} *)
{name: "Pedro Martinez",record: "23-4"} & {award:"Cy Young"} (*add a new
item to a record, returning {name:"Pedro Martinez", record:"23-4", award:"Cy
Young"} *)
1.4 & 2 (* returns {1.4,2}. Looks weird, but you might want to store a
long list of numbers in a list value type, then it doesn't seem so weird.*)
"Your AppleScript version is " & version (* Some concatenation operations
fail and need some massaging; "Your AppleScript version is " & (version
as string) will solve this problem *)
