See 3.1.6.3  Setting and Removing Conditional Job Breakpoints in the ILE RPG 
for AS/400 Programmers Guide.

In my view, one of the major flaws in the host debugger is that the debugger 
syntax is specific to the programming language being used. This idea might 
be fine if you program in one language but is a real pain in the arse if you 
use multiple languages. Therefore the debugger supports some things in one 
language that you cannot do in another, or you can do it but the syntax is 
different. Also, the debugger documentation is found in the Programming 
Guide for the particular programming language being used.

Nope, but I don't see why you would need that. The same effect can be 
achieved using %SUBSTR, for example:
        EVAL data = 'FIRST'
        EVAL %SUBSTR(data 11 10) = 'SECOND'

It gets worse if you are debugging C because a simple:
        EVAL charVar = 'NEW VALUE' 
won't work due C's stupid view of character data. You have to treat it as an 
array and set each single character element individually. Mind you the same 
problem exists with 1 char arrays in RPG so perhaps I shouldn't complain.

Simon Coulter.
