Hi Keven, I'm enjoying your Blog. If you, or anyone else is interested I would suggest a better way of going about Challenge # 11, is to put the messages in a table (80 character entries) and then write them out in a loop. e.g. the code to write the message could be (sorry , I don't know how to add comments as mono-spaced, so following will look a bit messy, please tidy up if possible): *----------------------------------------------------------- * program body *----------------------------------------------------------- OPEN (RECDD,OUTPUT) LHI 3,MSG#Q Number of messages LA 2,MSGTAB Address of first message LOOP MVC REC,0(2) Move message to REC PUT RECDD,REC Write message for disk AHI 2,MSGLENQ Bump on to next message BCT 3,LOOP Go round till all messages output CLOSE (RECDD) And the table could be: * table of 80 char messages MSGTAB DS 0C HELLOMSG DC CL80' Assembler Hello World! ' MSGLENQ EQU *-MSGTAB NEWMSG DC CL80'IBM Z is a complex instruction set' DC CL80'High level languages hide complexity of system assembler' MSG#Q EQU (*-MSGTAB)/MSGLENQ

I went down the same path with the shorter message. Just went back and fixed it. Over on the Slack channel for the contest, there’s a thread on this and either one is ok but extra points for using the continuation and printing the longer message.

Hi! K here.
I got the ‘system’ by just adding another line (another message) to the list of messages to have outputted. So I have four lines. I think it looks fine, but does anybody think I would have points taken off for not having just 3 lines?
Thanks

And the next line should definitely start from the 16th column, I forgot to add this after I’ve edited the message. If you need to add more lines, same process.

This is not an error on the challenge page. They only say it once, you have to output “High level languages hide complexity of system assembler”. If you want to write “system” as well you need a non-blank continuation character on 72th of the first line. It doesn’t matter if the character is right next to the statement, for example asse+
next line column 16: mbler”

Hi Kevin,

Yep, I think it is enough to put just 3rd line without system 🙂

I was also stuck on this task for a while, and just notice this suddenly 😀

What I can say, it is assembler, maybe there is limitations of symbols or something.

But it is good, that we know reason, so others can do this challenge quicker 🙂

Bets regards,
Viktor

Hello,
one ending character is missing from the end of this command:
call ‘z#####.load(asmhello)

Hi Viktor,

Oh wow, I never noticed that they left out “system”. That’s why I suddenly finished the challenge. I was stuck for quite a bit on this.

I don’t think we need to include “system” as the JCL doesn’t work with more characters than that. I would like to know though, but I don’t think they originally wanted that.

Kind regards,
Kevin
