Hello Shell Life and aigles,

Thanks to both of you for your time.

mPrtList="$1 $2 $3"
egrep -i "$SEARCH_STR" ./datafile.dat | awk -F: "{ print $mPrtList }"

I had tried this earlier but this seems to print all the fields in the selected records.

The one below seems to have worked Smilie
DISP_STR="\$1 \$3 \$5"
cat ./datafile.dat | grep -i $SEARCH_STR | eval awk -F: \'/$SEARCH_STR/ { print $DISP_STR } \'

This gives out only the columns asked for.

Thanks again for the response.
cheers

load_datafile

load_datafile(3alleg4)						  Allegro manual					    load_datafile(3alleg4)

NAME

       load_datafile - Loads a datafile into memory. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       DATAFILE *load_datafile(const char *filename);

DESCRIPTION

       Loads  a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate
       key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example:

	  /* Load the resources for our game. */
	  DATAFILE *dat = load_datafile("game.dat");
	  if (!dat)
	     abort_on_error("Couldn't load sound resources!");
	  /* Use resources. */
	  ...
	  /* Destroy them when we don't need them any more. */
	  unload_datafile(dat);

RETURN VALUE

       Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks.
