Size of pvx file

Hi,
i believe i have a chicken and egg issue here…

i have created a pvx file using pvanal.
The output is:
analysing 35280 sample frames (0.8 secs) from timepoint 1.0
frameSize=1024
1024 infrsize, 256 infrInc
135 output frames estimated
pvanal: creating pvocex file
20
40
60
80
100
120
140
160

Now i want to use this pvx file as a mask in an instrument, and i have to put it in a table.
But i do not know the table size, and deferred size is not allowed.
How can i get to know the table size of the pvx file?

filelen — Returns the length of a sound file! but not a pvx file
ftlen - deferred size for GENs 1, 2, 23, 28 or 49 only, so GEN 43 is not one of them
tableng - same thing as ftlen
