reading from 2 files using awk

hi,
Is it possible to read and compare 2 files which have different Field separators at the same time using awk???

file1:
1,dayal,maruti,Z-234,bangalore,KA,........
2,yash,esteem,Y-007,delhi,DL,...........
.
.
.

fill 2:
Z-234|Registered|Bangalore
Y-007|Registered|Bangalore
.
.
.

This is what the two files look like.
I need to compare the 4th field of the 1st file to the 1st field of the 2nd file.
Is there a way to specify the unique FIELD SEPARATOR/DELIMITER for each of the files while reading them in an awk?

Something like this?

awk '...' FS="," file1 FS="|" file2

Regards

oh cool thanks a lot man...
