Re: RPG hard to learn?

Steve - you are just so full of it sometimes. Why don't you try making a valid comparison for heavens sake.

There are RPG oriented libraries that would be every bit as easy to use as this - in fact sometimes a bit more obvious. This for example:
"$(elem).dialog( parms )
.prev(".ui-dialog-titlebar").css("background","yellow");"
Is hardly intuitive is it.

What library are you using? Where's the include or other configuration details to tie it together? Who wrote catLookup_GetHtm and what are the parameters about?

I guess we should be grateful that at least you are now on a "isn't json wonderful" kick instead of "isn't .Net wonderful" - at east it makes a change.

There doesn't _need_ to be more work for the RPG programmer than for any other programmer. Arguably, compared with Java for example, there's often a lot less work.

If you want to argue that learning old-style RPG so that you can be the next great JDE maintenance programmer is harder than other languages I'd be more inclined to agree - but it is the fact that those programs were written before many of the modern capabilities were introduced that makes the difference. Go look at Javascript from 15 years or so ago and tell me how easy it is to understand and maintain. i.e. code that was written before the language added a lot of the features that you now rely on.

I've taught modern RPG to C++, C#, .Net, Basic, COBOL, C, Java, and PHP programmers. NONE of them have had any problems with the language. Many (most?) of them learn to appreciate its strengths and use it where appropriate in their apps.

here is some javascript code. Think of how much RPG would be needed to
code the same thing.

catLookup_GetHtml( lookupSource, prCatNum, function( htmlText )
{
var elem = $(htmlText) ;

var pos = {
my: "left+50 top+50",
at: "left top",
of: elem
} ;
var parms = { height:500,
title:'Select Product Category',
close: dialog_Close,
width:550, position:pos } ;
$(elem).dialog( parms )
.prev(".ui-dialog-titlebar").css("background","yellow");
}) ;

I was reading a magazine article that was a thinly veiled advertisement
for a tool to migrate RPG to another language running on i. What really
caught my eye was "any developer can learn and use [language]", with the
implied contrast of "not every developer can learn and use RPG".

I learned RPG a long time ago, and for me it was "falling off a log
easy". What do you guys think, is RPG difficult?
