Truncate 4 characters from the end of a field

Question

How would I go about trimming the last for characters in a field.

Answer 1

If you are truncating it using the Picture, it should always work. If you are doing it via the !format event, does your data file have a field with the same name as where you put the code?
I have to admit I dont have a need for truncation so Ive not done any testing besides Test Presentment. The SSN sample came from an actual production form. There isnt anything Im aware of that has to be added to jfpreamble we dont have any form (out of 100s) that has custom jfpreamble coding.
FYI: We almost exclusively use global field definitions in our data files. If you are using field field definitions that might make a difference. For example, this is a sample from the end of a data file:
>...
^global Authorized_Rep_Name
G KOCH
^global TimeRequested
11:54:21
^global DateRequested
12/05/2006
^global 12_Address_lines
MRS BARBARA PRODUCTION
MODIFIED 5606 MARK
ADDRESS LINE3
SEATTLE WA 98679-8816
^global CP_IA_Record_No
9
^global CP_Address_lines_REC
9
^global DAT_File_Name
PF_0020_20061205_115421
^global DoNotMail
^FORM _base_page_v1r3.mdf
^field MannerOfServiceImage
C:\JetForm\Forms\FirstClass.jpg
^FORM f-01-115-v1r4.mdf
^FORM f-01-115-v1r4-s.mdf
^FORM sep-pg9-v1r3-cso.mdf
^FORM f-01-115-v1r4-cso.mdf
If we used field definitions it would look more like:
>...
^form 1111111
^field AAAA
DATA-AAAA
^field BBBBB
DATA-BBBBB
^form 222222
^field CCCCC
DATA-CCCCC
^field BBBBB
DATA-BBBBB
In the first example the data is only defined once, followed by the forms it is to be applied to. In the second example if the data appears on two forms it has to be defined for each form.
I dont know if this would cause a difference in your truncation problem.
