Strings

String concatenation​

String concatenation is made using the + operator. Examples:

"ab" + "cd" + "ef";
"ab"+12+"de";
"ab"+1+2

The first argument of a cocatenation with + must be a string:

   1+2+"ab"

String matching​

These functions match a string against a pattern:

   like(Charstring string, Charstring pattern) -> Boolean
   like_i(Charstring string, Charstring pattern) -> Boolean

In a pattern * matches sequence of characters and ? matches a single character. The [chars] pattern matches any character in chars. The function like() is case sensitive and like_i is not.

Examples:

like("abc","??c");
like("ac","a*c");
like("ac","a?c");
like("abc","a[bd][dc]");
like("abc","a[bd][de]");
like_i("AbC","a*c")
