Re: Need help in generating an instruction list

I will not tell you how to deal with your particular case. When I have 
to generate a tricky and/or long InstructionList, I:
1. Check how to generate the least: may be some runtime support methods, 
then some appropriate invokations; or even ready code, from a template 
method to where I need it.
2. When I am confident that I have found "the least effort" approach, 
write a method (in Java) featuring most of the code I have to generate, 
and investigate it using CCK; CCK is avilable with BCEL distro.
3. Spent several hours making the code working and my hair white.
4. Post messages like this to the BCEL Developers List

Last 2 steps are optional:)
