[en] Subroutines are created which enable the program written in the FORTRAN-4 language, to use more completely resources of the ES-1010 operational system. LA, NEM, MOVE subroutines permit the call-program to use monitor tables, to create and use data arrays, positioned in an arbitrary point of memory, to operate with an absolute memory addressing, to realize the interaction of programs connected with different interruption levels of the ES-1010 system. DC10 subroutine executes the information exchange with any zone of the system magnetic disc. The ARIN subroutine permits to introduce floating point constants without format. The given subroutines facilitate using the high level language (FORTRAN-4) at creating programs for receiving and primary processing physical information for the ES-1010 computer
