1.A specialized service routine designed to read an input stream, store programs and data on random access storage for later processing, identify the control information contained in the input stream,and store this control information separately in the appropriate control list.
2.Its major feature is to reduce EMS memory allocation greatly by the help of two one dimensional arrays: one is used to deposite the elements within the band width of the matrix at input stage and latter store the elements within the band width of cholesky lower triangle matrix at output stage;
