Need some java -> nrx help please...

Struggling again with some java code (part of a larger conversion that sofar seems to work…) to convert to nrx: mqcfh = new MQCFH(msg); for (int i = 0; i < mqcfh.parameterCount; i++) { PCFParameter pcfParameter = PCFParameter.nextParameter(msg); Object o = pcfParameter.getValue(); if (o instanceof String) { String srh = (String) o; System.out.println(/* * pcfParameter.getClass().toString() * +":" + */srh); } } I tried the ‘leave out the type’ and ‘new’ but, that doesn’t seem to do the trick here… Any help is appreciated J Michael _______________________________________________ Ibm-netrexx mailing list [hidden email] Online Archive : http://ibm-netrexx.215625.n3.nabble.com/ |

Letting java2nrx do most of the heavy lifting renders this:
mqcfh_ = MQCFH mqcfh_ = MQCFH(msg) i = int loop i = 0 to i + 1 while i << mqcfh_.parameterCount
pcfParameter_ = PCFParameter pcfParameter_ = PCFParameter.nextParameter(msg)
o = Object o = pcfParameter_.getValue()
if o <= String then do srh = String
srh = String o
System.out.println(pcfParameter_.getClass().toString() || ":" || srh) end
end Note: NetRexx is still case insensitive (kind of) so it's not a big fan of things like mqcfh = MQCFH() etc.
Alan. PS. I faked out the dependent classes and got it to compile and run too.

On reflection I think :
loop i = 0 to i + 1 while i << mqcfh_.parameterCount
should be changed to: loop i = 0 by 1 while i << mqcfh_.parameterCount

In reply to this post by alansam
Alan, Thanks! That did the trick! I am completely lost when it comes to Java and structures like this, I googled java2nrx and found kenai with sources, but no simple ‘run’ command to execute and find out… Did I miss something obvious? Would it be possible to put up a java2nrx web page where you can simply paste some java code and have it converted to NetRexx? I am sure I am not the only one running into this kind of problems… things that seem simple and obvious to java programmers are not as clear to me… That’s why I program in NetRexx ;-) Michael From: [hidden email] [mailto:[hidden email]] On Behalf Of Alan Sampson Letting java2nrx do most of the heavy lifting renders this: mqcfh_ = MQCFH mqcfh_ = MQCFH(msg) i = int loop i = 0 to i + 1 while i << mqcfh_.parameterCount pcfParameter_ = PCFParameter pcfParameter_ = PCFParameter.nextParameter(msg) o = Object o = pcfParameter_.getValue() if o <= String then do srh = String srh = String o System.out.println(pcfParameter_.getClass().toString() || ":" || srh) end end Note: NetRexx is still case insensitive (kind of) so it's not a big fan of things like mqcfh = MQCFH() etc. Alan.

I don't remember now where I got my copy of java2nrx (possibly from when I downloaded the NetRexx source from Kenai) but what I have is a command line tool. It comes with a bash script and a Windows BAT file and is pretty easy to use.
Bear in mind that for anything but the simplest programs it does need a lot of post-conversion clean up. Even the sample you sent wasn't valid NetRexx at first and as can be seen from my first attempt you need to scan through the resulting coe with a fine tooth comb to catch some gotchas; and its handling of Java anonymous inner classes can leave you scratching your head.
It still beats conversion by hand thouh so in the main it's worth it if you absolutely must have a NetRexx version of a program. Alan. PS With regard the loop construct from the conversion. Were I doing it by hand I wouldn't use:
loop i = 0 to i + 1 while i << mqcfh_.parameterCount ...
end loop i = 0 by 1 while i << mqcfh_.parameterCount
... end A more concise and Rexx-like construct would be: loop for mqcfh_.parameterCount
... end which allows you to drop the definition for the loop controlling variable i too.
