There is a variable in the format 9(4)V9(2) which has the first byte as the SIGN. It is to be converted to the format S9(5)V(2).

Hi,
We can't have negative sign in the first byte of data format 9(4)V9(2).
only positive values we can store in this format. So here no point to transfer sign to other varriable

Hi Viv,

The best way to get an ans, is to show us how the field looks in storage. Then we may be able to advise you as to how it should be defined.

For example show us each char as 2 4-bit peices (nybbles) of each byte. +153 will appear as follows in storage (I'm not sure about the + sign value, but you get the idea):
