The _TRIM$ function removes both leading and trailing space characters from a STRING value.
Syntax
- return$ = _TRIM$(text$)
Description
- Shorthand to using LTRIM$(RTRIM$("text"))
- text$ is the STRING value to trim.
- If text$ contains no leading or trailing space characters, it is returned unchanged.
- Convert fixed length STRING values by using a different return$ variable.
Examples
Example: Demonstrating how _TRIM$(text$) can replace LTRIM$(RTRIM$(text$)):
text$ = SPACE$(10) + "some text" + SPACE$(10) PRINT "[" + text$ + "]" PRINT "[" + RTRIM$(text$) + "]" PRINT "[" + LTRIM$(text$) + "]" PRINT "[" + LTRIM$(RTRIM$(text$)) + "]" PRINT "[" + _TRIM$(text$) + "]" |
[ some text ] [ some text] [some text ] [some text] [some text] |
