David,

The C APIs are actually pretty easy to use, but as Henrik says, you can use
plain ole' RPG to do much of what you want. I have a bunch of RPG
procedures to do memory scanning/replacing/trimming etc. Want them?

David,

what are you analyzing and how do you need to manipulate the data ?

Can you give a breif description of the task ?

Can you use a user space? That gives you 16 Mb.

Folks:

I've got a problem where I need to analyze and manipulate very large
blocks of character data.

This character data could be well in excess of 64k.

Since the limit for RPG character fields on 5.4 is 64k ... I can't use
normal BIF's.

Upgrading to 6.1 isn't an option due to customer requirements (this was
my first idea, but it got shot down).

My current thought is to use pointers and C functions to analyze the
text in the space.

%alloc to create space and get a pointer

strstr in place of %scan(s)
strlen in place of %len(%trim(s))
strcat & %realloc in place of s1 + s2
strncpy in place of %subst

dealloc when I'm done with the space.

Obviously I would wrapper the C functions in procedures so I don't have
to deal with the individual C api's directly.

I'm not supper happy with the idea of having to deal with this data
using pointers and C api's ... Any suggestions on a different approach to
handling these large character variables?

Thanks!

david
