RE: packed decimals -- JAVA400-L

byte dollars69 = 105;
 
"\u0001" will actually give you a NUL followed by an STX, but you may not
see the NUL depending on what you meant by "write" and "getting".

<snip>

How can I do something like this in java:

D $69             S              1A   inz(x'69')  

This a RPG declaration of a character variable $69, one byte long,
initialized to  x'69'.  

When I write the "\u0001", I seem to be getting something that looks like
the STX character X'01'.

 

Regards

 

Teresa
