to discard the 1st two lines of your input file because they contain headers that you don't want included in your output, that the '%.2f' didn't really appear in the command line you executed (since that would be a syntax error for nawk), that you don't really want the output rounded to five digits after the decimal point in the output (as would be done in your command line by OFMT='%.5f', and assuming that field #156 in the other lines in your input file contains a double quoted string containing a string of digits with no more than one period and with an optional leading minus sign (which you want to be ignored), you could try something like:
Code:
nawk -F'|' -v dqANDms='["-]' '
BEGIN { f=156
        printf("0")
}       
NR > 2 {gsub(dqANDms, "", $f) 
        printf("+%s", $f)
}
END {   printf("\n")
}' <File_Name> | bc

Hi Don !

Thanks for the work around solution and it is working fine for small files, but when I execute large files..facing below error:

Code:
 
0705-001: bundling space exceeded on line 1 stdin

Kindly help me in this regard.

Regards,
Ravichander

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
