C --
|
|
C --SORTID gathers the variables of the specified type into one area
|
|
C --of the /VAR../ arrays and orders these variables by IDVAR.
|
|
C --The variables are sorted at the start of the specified range.

C --
|
|
C --Parameters:
|
|
C -- STYP - IN - the variable type to be sorted
|
|
C -- ITOTAL - IN - the ending /VAR../ index of the variables to be ordered
|
|
C -- IBEGIN - IN - the starting /VAR../ index of the variables of type STYP
|
|
C -- IEND - OUT - the ending /VAR../ index of the variables of type STYP
|
|
C --
|
|
C --Common Variables:
|
|
C -- Sets NAMVAR, TYPVAR, IDVAR, ISTVAR, IEVVAR of /VAR../
