The LTRIM$ function removes leading space characters from a STRING value.
Syntax
- return$ = LTRIM$(text$)
Description
- text$ is the STRING value to trim.
- If text$ contains no leading space characters, it is returned unchanged.
- Convert fixed length STRING values by using a different return$ variable.
- Can be used to trim the leading space of a positive numerical value converted to a string value by STR$.
Examples
Example 1: Trimming a positive string number.
value = 12345 number$ = LTRIM$(STR$(value)) 'converting number to string removes right PRINT space PRINT "[" + number$ + "]" |
[12345] |
Example 2: Trimming leading spaces from text strings.
PRINT LTRIM$("some text") PRINT LTRIM$(" some text") |
some text some text |
Example 3: A TRIM$ function to trim spaces off of both ends of a string.
text$ = " Text String " trimmed$ = TRIM$(text$) PRINT CHR$(26) + trimmed$ + CHR$(27) FUNCTION TRIM$(text$) TRIM$ = LTRIM$(RTRIM$(text$)) END FUNCTION |
→Text String← |
