B.6.12 J1MDGR

 This subroutine determines the row in an SIM which has the maximum

degree. It examines all rows, counting their predecessors and succes-

sors. The SIM must be output set assigned.

B.6.13 JISIM

 This subroutine serves as an SIM generator. It accepts as input

a matrix stored in the SPACE COMMON area and produces in the SIM

COMMON the SIM equivalent to the original matrix.

B.6.14 J9PSCS

 This subroutine converts the Polish String representation of a

FORTRAN expression to the "Compute String" representation suitable for

evaluation by the subroutine EVALU8 (6.4). (This subroutine was

written by Westerberg [1974].)

B.6.15 PCKNME

 This subroutine accepts as data up to six characters stored in

separate words of a vector. It packs these characters into two words

of another vector, three characters per word. (This subroutine was

written by Cunningham [1973].)

B.6.16 RDDISK

 This is actually an alternate entry point to the IBM specific

subroutine WRTDSK (6.22). It reads data from a direct access data set

to MEMORY. The entire MEMORY vector is filled with data from the

direct access data set. The first record number from which data are to

be transferred is furnished by the calling routine.

B.6.17 SEARCH

 Another subprogram written by Cunningham (1973), SEARCH is an
