MASK FILE (NEED HELP)

[mysterdee]

Hi folks.

I am trying to make a mask File or a mask combination so that hashcat will only use certain letters and numbers 

basically  i need a mask for a brute force A-Z 3-9 but isolate (ILOSZ 0125)

for WPA/WPA2


I have not got a clue how to do this and i have been reading up about it but i only found out how to do and A-Z

-1 abcdefghjkmnpqrtuvwxy?d
-1 ?l 346789

so by rights

hashcat.exe -m 2500 capfile.hccap -1 ?l?d (this bit im stuck on)

is it -1 ?l?d

How should i do this mask?

Im stuck..

-1 ILSOZ 0125

is there not a way to do  ?u ?d -1


Does anybody have a clue for me.

Would be very great-full.

Thanks
