Re: Find a binary value with CL (V5R4)

Use %BIN to convert that byte to a numeric value. Then use multiplication, division and subtraction to isolate the bit.

Joe

Folks:

I am working on a project where I have to determine if a file is a
source file or physical file. The problem is it will be too slow to
call DSPFD to an outfile and read it for each of the files that will be
looked at. So I was trying to use the API QDBRTVFD which is perfect for
the problem, except: The data structure IBM used for the attributes is a
16 _BIT_ field. (Maybe Bruce can explain the logic behind that choice)



Constraints: Must use CL and must work at V5R4.

Any ideas how to get after that fifth bit?
