A block-oriented simulator program is described, which has been constructed for the solution of hybrid computation problems using a digital computer. The program simulates a high performance analog computer completed with continous and with intermittently working digital blocks which can be programmed and timed. The analog part is programmable in the form usual in analog computin.g techniques and the digital part in Fortran Language. The program could also run in consultative mode when the discretization time suitable for the given problem is proposed by the program itself. The program occupies 27.5 Kwords in the ICT-1905 machine core and overlays four times its program field. (Sz.N.Z.)
