incidence matrix stored in the SIM CNMMON area.

B.6.6 INLMEM

 This subroutine initializes the MEMORY COMM0N area. Its effect

it to erase all data in MEMORY.

B.6.7 INLSIM

 This subroutine initializes the SIM COMMON area, setting all

elements of the vectors to zero, except the lengths which are set to

unity.

B.6.8 INLSPA

 This subroutine initializes the SPACE C-7?llQi area. Its effect is

to erase all data stored there.

B.6.9 INSERT

 This subroutine inserts an element, at the indicated row and

column, into the SIM stored in the SIM COMMON area. An E-cell is

added and the appropriate H- and V-cells are expanded to reflect an

extra E-cell. H- and V-cells following the expanded ones are shifted

down by one word.

B.6.10 SPACE

 ISPACE initializes the SPACE COMMON area and resets all elements

of the work space vector, WORK, to zero, except the first word which is

set to unity.

B.6.11 J1DEGR

 This subroutine determines the degree of a row or column in an

SIM by counting its predecessors and successors. The SIM must be output

set assigned.
