7.3.3 BASIS--This control pennits a basis to be read in with hand punched
 cards that are represented by a series of names of primal struc-
 tural vectors (column names) and primal artificial vectors (row
 names). The program then extends this to create a basis for the
 entire problem under the assumption that the associated solution
 is feasible. The code will ignore any name that does not represent
 a matrix column. INVERT and GO should be used after this for the
 solution. The basis vector names are punched in the following
 format allowing from 1 to 10 per card:
 columns 1-6 should be blank
 columns 7-12
 13-18
 19-24 Each of these fields can contain one
 25-30 name or be a blank field

 61-66
 If the names on the card are all primal structural names (actual
 column names of the A matrix), then columns 67-80 should be blank.
 If the names are artificial vectors (A matrix row names) then the
 six characters "ARTIF." must be punched in columns 67-72.


7.3.4 BASIS*'--This control permits a program punched basis to be read
 in. A basis, all of its data, and the "END" card are punched by
 the LCRAND program when a "PUNCH" control card is encountered or
 when an output condition of five or greater is used (see section
 7.2.1). All of the basis names are included with the expression
 "DUAL.." in columns 67 to 72 of cards containing dual vectors.
 A special data card with restart information is punched if the
 current solution is feasible.


7.3.5 FREQUE--TIlis control is used to establish frequencies with which
 certain actions are to be performed. The FREQUE card is followed
 by any subset of the following three cards:
 OUTPUT sets a frequency for performing special output (condition 6)
 INVERT sets the inversion frequency
 CUTOFF sets a maximum number of iterations to be allowed for
 working on this problem.
