Importing a Cobol file

pic s9(11)v99

so length is 13 with a decimal point inserted between 11th and 12th numeral.

However the data looks like

000000157347A

or

000001798307{

with either an alpha or a ( as the 13th character

00000015734.7A is probably not what I should end up with. (don't think it's hexadecimal as alpha only appears as 13th)

Can't find any Cobol examples that have the trailing alpha or ( in them.

Any one have any ideas.
