eager Assembly learner

Postby misterbiswas » Sat Oct 26, 2013 10:28 pm

Hi all,

I want to learn S/390 Assembly. When I searched in the web I found this site and I think u guys can be really helpful.

My question is :
(1) I want an IDE where I can write S/390 assembly code and run in my PC. Is there any IDE available ? then what is it ?
(2) Can u guys please provide an S/390 sample assembly code (ex: a 'Hello world' program) ?

Your help is highly solicited. Thanks.

Look at http://www.z390.org for an emulator, which includes a Hello World program.

About the only PC oriented IDE I'm aware of is z390. It's Java based and needs an up to date Java installed on your computer. For execution, it sort of emulates ESA/390 (that's a machine) running a very stripped down OS/390 (that's an operating system). Here's a Hello World program designed to run in batch.
HELLO    CSECT
         USING *,12
         SAVE  (14,12),,*
         LR    12,15
         LA    15,SAVEAREA
         ST    13,4(,15)
         ST    15,8(,13)
         LR    13,15
         OPEN  (PRINT,OUTPUT)
         PUT   PRINT,MSG
         CLOSE PRINT
         L     13,4(,13)
         RETURN (14,12),T,RC=0
SAVEAREA DC    18F'0'
PRINT    DCB   DSORG=PS,MACRF=PM,DDNAME=SYSPRINT,RECFM=FBA,LRECL=121
MSG      DC    CL121' HELLO WORLD'
         END   HELLO

SAVE, OPEN, PUT, CLOSE, RETURN and DCB are all macros, not machine instructions. I'm pretty sure they are supplied with z390.

I've never tried running z390 myself, but many people think well of it. Good luck.

before posting did You care to read the topic You appended to ?

the TS asked for an IDE and the replies he got implied that there are none?

at most You might get an editor capable of highlighting, nothing more
