awk's efficient program

I am using gawk5 at the Windows 10 command prompt.

There are 10 files from ss1.txt to ss10.txt, and 10 corresponding awk programs from fff1.awk to fff10.awk.

If you run them in a batch file, you get 10 lines.

gawk-b-ffff1.awkss1.txt
gawk-b-ffff2.awkss2.txt
gawk-b-ffffff3.awkss3.txt
　↓ (Interim Omission)
gawk-b-ffff10.awkss10.txt

I wanted to summarize this compactly, so I created the test.awk below, but I think it is slow and inefficient because I start the child gawk with the system function from gawk.

test.awk

BEGIN{
for (i=1; i<=10;i++)
{
cmd = "gawk-b-ffff "i".awk "ss "i".txt"
system(cmd)
close(cmd)
}
}

I can't create a system function or a method that doesn't double-start gawk.
Please advise me on a good way.Please.
