You can find the info using PROCINFO["argv"]:

| $ cat > /tmp/f1
| BEGIN { print "f1" }
| $ cat > /tmp/f2
| BEGIN { print "f2" }
| $ cat > /tmp/f3
| END {
|       for (i = 0; i in PROCINFO["argv"]; i++)
|               print i, PROCINFO["argv"][i]
| }
| $ gawk -f /tmp/f1 -f /tmp/f2 -f /tmp/f3 /dev/null
| f1
| f2
| 0 gawk
| 1 -f
| 2 /tmp/f1
| 3 -f
| 4 /tmp/f2
| 5 -f
| 6 /tmp/f3
| 7 /dev/null

Hope this helps,
