LIKE
Result = Expression [ NOT ] LIKE Pattern AS Boolean
Returns
TRUE if the
Expression string matches the
Pattern string.
If
NOT is specified, the test is inverted.
The pattern is not case sensitive, and it can contain the following generic characters:
|
Generic character
|
Matches
|
|---|
*
|
Any number of any character.
|
?
|
Any single character.
|
[abc]
|
Any character between the brackets.
|
[x-y]
|
Any character in the interval.
|
[^x-y]
|
Any character not in the interval.
|
|
space
|
Any number of spaces or characters with an ASCII code lower than 32.
|
{aaa,bbb,...}
|
One of the strings between the curly brackets. The strings are separated by commas.
|
\x
|
The character x, even if it is a generic character. Use this for matching a generic character.

Examples
PRINT "Gambas" LIKE "G*"
PRINT "Gambas" LIKE "?[Aa]*"
PRINT "Gambas" LIKE "G[^Aa]*"
PRINT "Gambas" Not Like "M{$,onsanto,afia}"
You must double the backslash character, otherwise
\* will be interpreted by the compiler as a special character like
\n,
\t, ...
Or you can use this pattern string:
LIKE "G[Aa][*]"
PRINT "Gambas" LIKE "G[Aa]\\*"
LIKE only deals with ASCII strings. If you need to match UTF-8 strings, use the
gb.pcre component.
