Name:
trim$() -- remove leading and trailing spaces from its argument
Synopsis:
a$=trim$(b$)
Description:
The trim$-function removes all whitespaces from the left and from the right end of a string and returns the result. Calling trim$ is equivalent to calling rtrim$(ltrim$()).
Example:
do
input "Continue ? Please answer yes or no: " a$
a$=lower$(trim$(a$))
if (len(a$)>0 and a$=left$("no",len(a$)) exit
loop
Explanation:
This example asks for an answer (yes or no) and removes spaces with trim$ to make the comparison with the string "no" more bulletproof.
