Usage-- Lingo syntax
expression1 & expression2
// JavaScript syntax
expression1 + expression2
DescriptionString operator; performs
a string concatenation of two expressions. If either expression1 or expression2 is
a number, it is first converted to a string. The resulting expression
is a string.
This is a string operator with a precedence level
of 2.
Lingo allows you to use some commands and functions
that take only one argument without parentheses surrounding the
argument. When an argument phrase includes an operator, Lingo interprets
only the first argument as part of the function, which may confuse
Lingo.
Avoid this problem by placing parentheses around the
entire phrase that includes an operator. The parentheses clear up
Lingo’s confusion by changing the precedence by which Lingo deals
with the operator, causing Lingo to treat the two parts of the argument
as one complete argument.
ExampleThis
statement concatenates the strings “abra” and “cadabra” and displays
the resulting string in the Message window:
-- Lingo syntax
put("abra" & "cadabra")
// JavaScript syntax
put("abra" + "cadabra");
The result is the string
“abracadabra”.
This statement concatenates the strings “$”
and the content of the price variable and then
assigns the concatenated string to the Price field cast member:
-- Lingo syntax
member("Price").text = "$" & price
// JavaScript syntax
member("Price").text = "$" + price;
