Quick answer: just save the variable you need in a new database (they are very few).

For example, I would like to use the series 5, 8, 37 and, 98 and delete anyone else. Please take a look in this pseudo-code:

list Y = 5 8 37 98

if the variable is on the list
make nothing
else
delete variable
endif

the trouble with this script (if it does actually work) is that every time a variable is deleted all remainng variables are being renumbered. For example, once you delete the 1st variable (whose ID is 5) the 8th variable becomes the 7th.
Better if you only save the variable you need as Leandro pointed out.

whatever the solution may be, the "delete" command seems unavailable in loop mode.
