Hi All,
Just to elaborate on the above answers..offcourse CHGPF is
correct and we can just press enter on this command and it
modifies the object based on the current DDS keeping the
data intact. But there are a couple of things to be taken
care of in this:
1.> If we are increasing the field lenghts then there is no
problem at all and chgpf runs absolutely fine.
2.> If we are decreasing the field length, then in case of
character field it will give warning as the existing
records might be truncated because of the shortened length.
But in case of numeric field the caommand will fail because
OS400 cannot truncate the existing numeric data and the
command blows up.
3.> If suppose the command is successfully run and the
field length is changed in the PF then there r chances that
the LF wont reflect the change. If in LF Pfile is mentioned
and no fields (that means the whole record format is copied
from PF) then it will reflect the new length. But in case
you have mentioned certain fields in LF then it will keep
on showing the old lenght inspite of the fact that in PF
the lenght is changed. This is because here the field
attributes are copied to LF from the PF when it is compiled
and it keeps on showing that length only.
