Subject: RE: SQL find hexadecimal values in a given range

Can someone help me out here :

I want to declare the constant
x'000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D

3D3E3FFF'

But I can't seem to get the syntax right for it to occupy
several lines of source. Without the 'X' I can do it.

I really don't think SQL is the tool for this - if this is about
replacing non-displayable characters. You would be better off using
the %xlate function, I think. It is useful for simple case

conversion,

but you could set up 2 constants
- the first would be something like
x'000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D
1E1F202122232425262728292A2B2C2D2E2F303132333435363738393A3B3C
3D3E3FFF'
and the other would be all blanks and the same length -

remember that

the above value is in HEX, so it is 2 hex digits for each

"character"

or byte - you need the same number of blanks as there are

bytes above.

Then use %xlate - I don't have the exact syntax right in my

head - get

the ILE RPG manual. %xlate will do the read through the

entire string

and do the replace for you.

I do hope there is an easier way!!

SELECT locate( X'40', myfield, 1), myfield FROM myfile

WHERE locate(

X'40', myfield)>0

How can I find hex values less that 40?

Thanks
