Hi,

1 Ans: Whenever a program abends, it leaves some data in memory called DUMP. we can analyse this dump to find out why program abended. This dump will be available in SPOOL. Dump analysis has the following steps...

- Dump Format (Abend-Aid)
- Determining if the source and load modules match
- Finding the abend point
- Finding common storage items in a dump
- Finding uncommon (INDEXES, etc.) storage locations in a dump

2.Ans: Your que is not clear. As I understood U need 25 fields where screen can accommodate only 10 fields. If this is the case. Simply create another BMS MAP and link to that map when user press ENTER on MORE ( You code it in first screen). Refer to existing programs of your project. Usually every program will have more than one MAP.

3. What you know is right. But we cannot list all the utilities we have a lot. you can search for IBM Utilities to get a list.

IEBGENER
IEBCOPY
IEFBR14
IEHPROGM
etc...

Bye,
Reddy.
