Is My Assumption Correct - StringLen() syntax error

[B540glenn]

I have a script (V3.3.8.1) that selects records from a delimited file based on a field on the record. To do this I use:

…
$fields = StringSplit($line_text, '|', 1)
If $fields[0] > 0 Then
     $length = StringLen($fields[11])

MsgBox(0, "Display", "Input Field 11 " & $fields[11] & " " & $length)

    If $length > 0 Then
…

The syntax check in Scite returns no errors.

When I run the script it produces the expected output but I get this syntax error:

$length = StringLen($fields[11])

$length = StringLen(^ ERROR

The MsgBox displays a zero for those fields that are empty so why the error?

Is this because on some records $fields[11] does not exist?

If not, what is the cause?

Just trying to understand.

Thanks,

Glenn

The error text following ^Error describes what's going on. Can you post the text?

Once again, your socratic method has put the student on the correct path.

The message appearing above the syntax error, "Array variable has incorrect number of subscripts or subscript dimension range exceeded.:" pointed me to the field array, which, after reading all the records becomes 1 at the end of the file.

I will review my While Loop and end of file process and accomodate this situation.

Thanks for your help,

Glenn
