Arguments

A basis

A decision variable

A linear constraint

Basis status. For a variable:

-1	Remove the variable from the basis
0	Variable is non-basic at lower bound, or superbasic at zero if the variable has no lower bound
1	Variable is basic
2	Variable is non-basic at upper bound
3	Variable is super-basic

For a constraint:

-1	Remove the constraint from the basis
0	Slack, surplus or artificial is non-basic at lower bound
1	Slack, surplus or artificial is basic
2	Slack or surplus is non-basic at upper bound
3	Slack or surplus is super-basic
