Return value
String.
Returns the characters for the leftmost n bytes in the source string
if it succeeds and the empty string (“”) if an error occurs. If any
argument’s value is null, LeftA returns null. If n is greater than or
equal to the length of the string, LeftA returns the entire string. It
does not add spaces to make the return value’s length equal to n.
Usage
LeftA replaces the functionality that Left had in DBCS environments
in PowerBuilder 9.
In SBCS environments, Left, LeftW, and LeftA return the same
results.
