To check whether a string begins with a particular sequence of characters, use the function
match ( t, s )where t is the target string to be searched for, and s is the string to be searched.
match()
'' function fails.
For example, the expression
match ( "foo", "rumplestiltskin" )fails, while the expression
match ( "foo", "foobar" )succeeds and returns the value 4, which is the position just to the left of the
"bar"
in the second argument.
