Trim$(A$[,"char"])
The Trim$ internal function can be used to delete both leading and trailing blanks from the string A$. Trim$(A$) returns the same value as RTrm$(LTrm$(A$)). The optional "char" parameter can be used to specify the character (instead of blanks) to strip; this parameter is limited to one character in length. Nulls (Chr$(0)) are allowed.
Example
00010 print trim$(" The leading blanks will be removed. So will the trailing ones ")&"..."
00020 print trim$("*****The leading stars will be removed. So will the trailing ones******","*")
Output:
The leading blanks will be removed. So will the trailing ones... The leading stars will be removed. So will the trailing ones
