Dear Ernie,

You can find any character you want by using the Clean, $findclean and 
$clean feature. The first issue to deal with is to re-define the 
item-number as a byte type in order to use the function.

The following shows how to find the fields with "invalid" zoned-decimal 
characters. Remember that zoned fields use characters to indicate the 
sign, it's likely that you don't have negative Item numbers but they are 
valid.

get somedataset
def item-x,item-number,byte
{Setup what characters to look valid characters are 0-9, JKLMNOPQRST, 
ABCDEFGHI and the curly braces }
{ so Clean characters should be not the above }
clean "^0:^47","^58:^64","^85:^122","^126:^255"
if $findclean(item-x)
ext item-x
list st
xeq

Note the clean command defines the "decimal" characters to look for.

See the online manual for more information on the clean feature.
