RE: SQL find hexadecimal values in a given range

Thanks a lot Vern, I've at least found some records that were causing problems.

// Translate unwanted characters to spaces.
MyNewField = %xlate( before : after : MyField );

// write the record containing the unwanted characters
IF MyNewField <> MyField;

WRITE myfile;

ENDIF;

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
