Bug issue in calculation

Hi all

Already posted this question,i belive i didn't exactly said my question.

I have data files it stored in the different path like
/st/vr/sum.dat
/st/vr/pass.dat
/st/vr/fail.dat

we are not suppoe to mention the hardcode value of the path.

I need to calculate the percentage of pass and fail.

so in my shell script i wrote like

total=$datafile/sum.dat
pass=$datafile/pass.dat
fail=$datafile/fail.dat


i tried in this way:
exp1=$SCR_DIR/$equal_count.dat/$EQUAL_COUNT*100
echo $exp1 | bc

and created an awk script : percentage.awk
{
printf ("%3.2f%%\n", $2/$1 * 100)
exit
}

like this and called through the shell script like

awk -f percentage.awk -v $total -v $pass > pass_percentage.dat

this is also not worked.

if the echo stament is fail to fetch the address of the exp1 and it's not calculating the percentage.

please advice me on this.

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. SEE ALSO
