Re: getBytes for a string longer than 65535

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

RPG strings can only support 65535 chars, so the idea of converting a Java 
string longer than 65535 to RPG doesn't completely make sense.  How can 
you convert it to an RPG string, if RPG doesn't support strings that 
large?

Now, if you want to store it into memory allocated to a pointer, or a user 
space, or some other construct that doesn't have the 65535 limitation, you 
could -- by calling the JNI functions GetStringLength() and 
GetStringChars().  This'll give you Unicode data, and you'll need to 
convert it to EBCDIC -- RPG's UCS2 support should be able to do the 
conversion.

Or, you could call GetStringUTFChars() and you'll get memory that's 
dynamically allocated containing a C-style null-terminated string in 
UTF-8, already dynamically allocated to a pointer. You could use the 
%STR() BIF in RPG to convert it to an RPG-style string (albeit, still in 
UTF-8) and ReleaseStringUTFChars() will return the dynamic memory to the 
system.  But, you'll have to use iconv() or a similar function to convert 
it to EBCDIC.

So, it's not easy, but possible...
