if i <= length(s1) and j <= length(s1[i]) and j <= length(s2) and k <= length(s2[k]) then 
    s1[i][j] = s2[j][k] 
else 
    return false  -- oh dear, give up 
end if 

I get it. You are using "error" to mean "fatal error" whereas I am using the phrase "error code" to mean exactly that kind of long-winded and tedious code, which to be fair can itself be a source of unwanted errors. Wanting something neater is fine.

Sure. But we ought to be cautious about over-selling this as some easy panacea. There will be cases where the long-winded and tedious approach turns out to be simpler, in the long run. We must still give a user an adequate warning about saving a possibly corrupt document even if it is annoying. Doing and saying nothing can be even more annoying than an abrupt crash. If there is a nasty bug that causes our program to quietly go bananas in the field, we still need to know about it. And so on.

Oh, I just meant any-named user-defined routine with whatever parameters you might want or need containing common code factored out from the try and catch blocks.

I thought you were having a dig at my use of italics when I first read that
