Examples

1. This example returns 0. The underscore matches only a single character.

   @Like( "A big test" ; "A_test" )

2. This example returns 1. The five underscores match "<space>big<space>."

    @Like( "A big test" ; "A_____test" )

3. This example returns 1. The % matches "A big ."

   @Like( "A big test" ; "%test" ) 

4. This example returns 1 because the match is true for one element of the first parameter.

   @Like( "A big test" : "A big exam" ; "%test" )

5. This example returns 0. @Like is case-sensitive.

   @Like( "A big test" ; "A BIG test" )

6. This example returns 1. The first percent matches "100." The "/%" matches the percent sign because "/" is specified as the escape character. The last percent matches "ement."

   @Like( "A 100% improvement" ; "A %/% improv%" ; "/" )
