Get all File names starting with letter P

Hi,
I have lets say 10 files , I need to process them one by one.
So I need a command to get one file name at a time to process it into a variable

Example
Files
P1111.dat
P3344.dat
S344.dat
...

v_file_name = 'p111.dat' .. I will rename it to something after processing

second iteration v_file_name = p3344.dat

Etc.

Thanks would really appreciate your help

Code:
cd $HOME
for file in $HOME/[pP]*.*
do 
  echo $file 
done
