C --*** LNKVAR *** (ALGEBRA) Link equation references with variables
|
|
C -- Written by Amy Gilkey - revised 11/30/87
|
|
C --
|
|
C --LNKVAR links the variables in the equation with the /VAR../ arrays.
|
|
C --Each equation variable (from /ENT../) is found in the /VAR../
|
|
C --arrays, and the /VAR../ index is stored in the INXENT array.
|
|
C --Note that since the /VAR../ arrays were constructed from the
|
|
C --equation variables, each variable will be found.
|
|
C --
|
|
C --Parameters:
|
|
C -- * - return statement if an error is found; message is printed
|
|
C --
|
|
C --Common Variables:
|
|
C -- Sets INXENT, VALENT of /ENT../
|
|
C -- Uses NAMENT, TYPENT of /ENT../
|
|
C -- Uses NAMVAR, TYPVAR, IDVAR, ISTVAR, NUMINP, IXLHS of /VAR../
