Symbols used

Xs sth independent variable (s = 1 or 2). Its values are real.
X1 is the bounded independent variable, X2 the unbounded independent variable.
To each value of X2 corresponds a different set of regularly spaced values of X1 defined by their number, base value and increment.
NX Number of values of X1. It is X2-dependent.
If NX(m) = 0, there is no record of Vn at the mark X2(m).
X1(1,m) First value of X1 at the mark X2(m). It is X2-dependent.
DX1 (Regular) interval of X1. It is X2-dependent.
NV Number of primary dependent variables
NAUXV Number of auxiliary dependent variables
Vn nth primary variable
Aa ath auxiliary variable (depends on X2 only — independent of X1).
A1 = NX (integer).
A2 = X1(1)
A3 = DX1
For a > 1, Aa is real.

Condensed notation

[ X2(m) NX(m) X1(1,m) DX1(m) ( Aa(m), a=4,NAUXV ) ]
[ Vn(i,m), i=1,NX(m) ] n=1,NV [Omitted if NX(m) = 0 or if NX(m) = AMISS1]
