"What operating system do you have?"
"UNIX"
"What model of car do you have?"
"Blue"

Very, very vague answer. But that you have BASH tells me enough, I hope.

You can do this in one command instead of five plus a temporary file. Tis also makes it more flexible since it chooses the right files depending on the name.

Code:
$ awk -v X="IS38341" -v Y="BACBE03" 'BEGIN {
        while(getline < ("stp_" Y ".txt")) if($1 == X) { A=$2;  break   }
        while(getline < ("tx_" Y ".txt")) if($2 == X) C++;
        printf("%s,%s,%s,%d\n", X,Y,A,C);
        exit
}' /dev/null

IS38341,BACBE03,ACTIVE,4
