I am trying to read a file through the command
path='C:\LWP\'
file=dialog_pickfile(PATH =path,filter ='*TXT')
which has data to read and it is stored in some array.
The file names in the "PATH" folder has a sequence "A1.txt", "A2.txt", .... and 15 others.
Now I want to store the data in some another file.
I want to store data in a new sequence such as "MA1.txt", which suggests the file has been read.
so i want to add "M" in the newly saved file name along with old file name.
EX:
"M"+ "(original file name)".TXT
Is it possible in IDL 8.4 Win PC ?

Since the output of dialog_pickfile() is a string you can use strmid() to remove the path. For example,
IDL> print, file
C:\LWP\A1.txt
IDL> print, strmid(file, 7)
A1.txt
IDL> print, 'M' + strmid(file, 7)
MA1.txt
Further info on strmid() and other useful routines:

Or file_basename().
