| Str.Trim | Part of Str module |
| Syntax | Str.Trim (str : string) : string |
| Description | The Str.Trim function takes the string str and returns
a string in all the leading and trailing spaces (the spaces at the
beginning and the end) are deleted. For example,
Str.Trim (" This is a test ") returns
"This is a test". If str only has spaces in it, then
Str.Trim will return an empty string.
|
| Example | This program obtains input from the user until the user enters a line
with non-whitespace characters in it.
var line : string
loop
put "Enter a non-empty line of text: " ..
get line : *
exit when Str.Trim (line) not= ""
end loop
put "You entered ", line |
