Thanks for responding.But still there is some doubt.For removing garbage values we can move only low values(i.e spaces) if I am correct.Then why do we go for High Values and what are these high values.Can you please illustrate it more?

Hi Madhu,
Just a note: Low values is not equivalent to spaces on all the installation.

Low values is lowest value in the collating sequence and high values is highest values in collating sequence.

Moving low values and high values are helpful in initialization of records....

Huum,

Balaji is right.

It is useful to move low/high values while processing VSAM files.

When we want to start processing the VSAM files sequentially, low values should me moved first and then START/BROWSE or read operations should be issued...

Thanks,
Parikshit.

Hi Parikshit,

Your answer implies that only in the case of VSAM files these high and low values are moved.What about Non VSAM files?

Thanks,
Madhu

Hi Madhu,

For VSAM, NON-VSAM, DB2 , NON DB2 also it will work.
