type meaning length offset
---------------------------------------------
var. 1 98 str98 98 0
var. 2 136 str136 136 98
var. 3 102 str102 102 234
var. 4 105 str105 105 336
var. 5 102 str102 102 441
var. 6 98 str98 98 543
---------------------------------------------
sum 641
The width of an observation (a.k.a. lrecl) is 641 bytes. The approved
method is to read the data an observation at a time, in 641 byte
chunks.
I will now use C jargon. Let (unsigned char *) buf[] contain one observation.
You can then extract each variable using memcpy(), using the offsets and
lengths from the table above. Once extracted, if numeric, and if bytes need
reordering, reorder them. If string, add a binary 0 terminator in case one is
missing.
This should be easy to code, but you will have to build a table in your
code to direct what needs to be done.
