Hi, Does anyone know how to view JCL code on the mainframe using TWS? I know there is a way by naming a JCL Edit Tool Panel but I don't know where to find the Panel names. Are there any other ways to view JCL without using Edit Panels?

I'm looking for some background on I/90(Insure/90). I know it is Insurance related and runs on the AS400 but is it just an Insurance front end software? A year ago I think I saw something on IBM's site but I can't find it anymore. I tried Google and found ads for I/90 developers and a few...

I know there's quite a difference between RPG and RPGLE but what is the difference between CL and CLLE? One thing I do know is that the Source File, Library and Member fields in the compiled object become blank and until 7.1 you can't recover the source for CLLE. Does anyone have a link to...

Which is better and which is best practice? I've never used PRTF before and the client I used to work for used O-specs in their programs. Most of their printouts are only used by one program so PRTF weren't used. When do you use PRTF? Ever worked with multiple programs that shared one PRTF?

Hi, I've been asked to recreate a TSO REXX program in the AS400. I'm not too good with TSO commands so I don't know the AS400 commands that I need to use. I know not everything in TSO REXX applies to REXX400 like OUTTRAP. I wanted to start slow and made a program that will check if the...

When is it best to compile a program as a module and when is it best to compile as Service program? I know that copybooks, modules and service programs encourage reuseability of code and that copybooks are members that can contain reuseable D-specs and that you don't compile copybooks. Can...

What other languages are alive and useable on the AS400 post System i 6.1? I've read somewhere that BASIC, Pascal and PL/I support stopped somewhere in v4. The list of languages I found includes: Assembly, RPG, CL, COBOL, RPGLE, Java, C, C++, Perl, EGL, Smalltalk, SQL, BASIC, PL/I, Python...

The presence of a N on Position 21 of the Output Specs has me a bit confused. I know that putting an indicator number on pos 22-23 means that the line should be printed if the indicator is on. Does having a indicator preceded by N in the O-spec mean the line should be printed if the indicator...

I'm trying to merge several lines in one file so that it prints out as one record in another file. Something seems to be making my code go into infinite loops though as it is taking my program almost 300 seconds to run and that only because I ended the job manually. The program is supposed to...

I have a order report that prints the summary lines first before it prints the detail lines. The report works fine so long as there is only one line per order. The problem comes up when there are multiple lines for one order. Since the summary is written first before the detail only the first...

Does anyone know how to use the UNDEL2 freeware tool? I was able to download it to my PC, FTP it to the AS400 and restore the UNDEL2 library. I also did the CHGCMD but I still can't call on the command though. I'm using a V5r3M0 Any suggestions?

I've come up against situations where records were not processed because there were more than 1 result to a chain operation. The program I'm working on now generates an error report when records are not processed. The program doesn't catch the error when a Chain operation results in 2 or more...

Hi, When a numeric field is declared as 7 Length 2 Decimal it means the field contains a total length of 7 with 2 decimals leaving 5 numeric spaces to the left of the decimal point right?

I'm trying to look for a missing record. I think that it might have been deleted but I don't know when so I can't just restore the daily backup for the file. I know that it is possible to recover deleted records using DBU but it is only for one record at a time. Is there a way to do mass...

We have Hawkeye 9.0 installed in our AS400 and I'm currently using it to study the job flow during a batch job. I've been studying the EXPLODED file that is generated when Building a x-ref. I'm not sure if my understanding of the EXPLODED is correct but it looks like Hawkeye reads a program and...

I have a piece of program that checks a file to see if a record exists and displays a message on the screen for the user if it doesn't. The message asks the user to press F12 to ignore the issue but looking at the code I don't think the logic for the continue exists. Below is the bit of code. I...

I executed a CPYF to copy a new file and gave it a new name. The record format of the new file is the same as the old file. Does anyone know how rename a record format of a Physical file without a DDS?
