View Ref-File7.2.4.3  Bit-image drivers                                         TOS

With the aid of a bit-image driver, all applications that can output 
via GDOS can print directly to a file.

With NVDI drivers, one can set the page format and the name of the 
bit-image file for v_opnwk. The filename can also be passed with the 
help of vq_extnd:

contrl[1]   = 4;
ptsin[2]    = 1157;
ptsin[3..4] = Pointer to the filename (BYTE *);
ptsin[5..6] = Pointer to the error variable (int16_t *);
ptsin[7]    = 0;

Note: One can certainly argue about the sense or nonsense of this 
feature, since vq_extnd is actually a pure information function!
