[en] This report describes an expansion of the program of the data acquisition system for the 20 MV tandem accelerator. By the present expansion it became possible to change the accuisition mode or to use non-standard CAMAC modules with partial modification of the program according to well defined prescriptions. The modification can be made by writing microprograms for the MBD or appending subroutines for the reduced spectra in the LIST mode data acquisition. The new program can handle up to 32 ADC's in the standard LIST mode data acquisition. The present expansion aimed to increase the flexibility in data acquisition. It can also be applied to control experimental devices. (author)
