Hi All:

Quick question:  I have a 19 byte character field that contains only '0's and '1's.   Is there a quick (simple) way to sum the numerals in the field

to see how many of them are set to '1'.  This way if the sum is > 1 I know there is more than 1 byte not 'zero'.  Unfortunately, the field is a

character field and I can't change that.

Thanks in advance.

Hi:

The data is in a variable formatted like:  '0001001000110001000'   and I basically need to count the number of '1's.

I could use an array but that is messy.  Hoping for something simple.

Thanks.
