Combine mask attack with combinator

[monyanus]

I ended up generating all orders as mask myself, I used btcrecovery for this purpose, but a few for loops would do the same.
After a lot of trial and error, I got the definition of the custom characters in the mask file right, putting the lines below in the beginning of my mask file (but it did not work).
--custom-charset1: kmhdl
--custom-charset2: sfjPaGMi
--custom-charset3: DFgJLnopwztvxZKbec
--custom-charset4: CQRTYABSEqryIHNUuWOVX

In the end I had to change to defining per line the character set which if way less efficient if you ask me, this should be optional, not obligatory. Example of per line definition of the custom character set. Tip, you can easily paste it in front of multiple lines using sublime multi-line editing:
kmhdl,sfjPaGMi,DFgJLnopwztvxZKbec,CQRTYABSEqryIHNUuWOVX,?1?2
Which means character_set_1:kmhdl , character_set_2: sfjPaGMi, character_set_3: DFgJLnopwztvxZKbec, character_set_4: CQRTYABSEqryIHNUuWOVX, mask_pattern:?1?2

Based on reading the following information on masks and custom character sets

After getting the mask file to work I got a "cuMemAlloc out of memory" error
=>Based on this post:

Trying to clear some RAM, with 11 GB of VRAM, I should have at least 11 GB of normal RAM free.
=> Now running attack of 9 semi random characters
