LenA PowerScript function
Description
When the argument is a string, temporarily converts the string
from Unicode to DBCS based on the current locale, then calculates
its length in bytes. When the argument is a blob, no conversion
takes place.

|---|---|

stringorblob |
The string or blob for which you want |
Return Values
Long. Returns a long whose value is the
length of stringorblob if it succeeds and -1
if an error occurs. If stringorblob is null, Len returns null.
Usage
LenA replaces the functionality that Len had
in DBCS environments in PowerBuilder 9.
In SBCS environments, Len, LenW,
and LenA return the same results.
If you specify a size when you declare a blob, that is the
size reported by LenA. If you do not specify
a size for the blob, LenA initially reports the
blob’s length as 0. PowerBuilder assigns a size to the
blob the first time you assign data to the blob. LenA reports
the length of the blob as the number of single-byte characters it
can contain. Len and LenW report
the size of the blob as the number of double-byte characters it
can contain.
