There are four different types of output produced by LCRAND: short output,
row output, primal-dual output and BASIS*. The first three are types of
printed output and BASIS* is a basis for the problem punched on cards.
The PRIODE data card specifies what combination of the set of output choice
should be printed out for each of the ten possible stages listed above.
The data card for PRMODE contains a numeric code in each of the first ten
columns which describe the output desired for each of the ten conditions.
This numeric code and its interpretation is as follows:
 0. no output
 1. short output
 2. short and row output
 3. short and primal-dual output
 4. short, row, and primal-dual outputs
 5. card output for BASIS*
 6. short output and BASIS*
 7. short and row output and BASIS*
 8. short and primal-dual output and BASIS*
 9. short, row, and primal-dual output and BASIS*
Therefore, if the statements
 PRMODE
 0099944444
appear in the input stream, output will be performers as follows:
--no output after every pivot step or when feasibility is declared
--short, row, primal-dual and basis when optimality is declared, no
 feasible solution exists, or when an infinite solution exists
--short, row, and primal-dual for the other five conditions (stages).
The default settings by the program if the user does not include a
PRMODE card are
 0099969939
 There are two other special purpose type 1 control cards which
are used for parametric programming on the linear part of the objective
function in a QP model. This capability was built into the original
IRADQP and not discarded when the RANDQP was revised to create the LCRAND,
This particular type of parametric programming facility is useful in
RISK programming, but does not really apply in the market-oriented type
of economic modeling which is the focus of the examples in this manual.
