Hi Bob,


* Your data (Example).

DATA LIST FREE/V1 TO V10.
BEGIN DATA
1 1 1 0 0 1 0 1 0 1
0 0 1 0 1 1 1 1 0 0
0 1 0 1 0 0 1 0 1 1
END DATA.

* Method 1: Don’t look at the “9” of VARINT_1 or convert
* VARINT_1 into a string variable and drop the “9”.

COMPUTE w=9.
COMPUTE varint_1=
w*10**10 +
v1*10**9 +
v2*10**8 +
v3*10**7 +
v4*10**6 +
v5*10**5 +
v6*10**4 +
v7*10**3 +
v8*10**2 +
v9*10 +
v10.
EXECUTE.
FORMATS varint_1 (F11.0).
LIST varint_1.

* Method 2: The missing values in VARINT_2 before the
* first “1” are all zeros.

COMPUTE varint_2=0.
COMPUTE k=9.
VECTOR x=v1 TO v10.
LOOP i=0 TO k.
COMPUTE varint_2=varint_2+x(i+1)*(10**(k-i)).
END LOOP.
FORMATS varint_2(F10.0).
LIST varint_2.
