Syntax:
subString$ = left$(string$, numChars)
subContainer$$ = left$$(container$$, numChars)
Description:
This function returns a substring or subcontainer consisting of the leftmost numChars
characters of string$
or container$$
. If numChars
is greater than the length of string$
or container$$
, then left$
returns the entire string or container. If numChars
is zero, then left$
returns an empty (zero-length) string.
Note:
You may not use complex expressions that include containers on the right side of the equal sign. Instead of using:
c$$ = c$$ + left$$(a$$,10)
Use:
c$$ += left$$(a$$,10)
