I don't know what a block is precisely, or why you think we can work that out from this description, but more importantly I don't think dictionaries work with any concept of block. 

-infile- can be combined with -if- or -in-, which may allow progress. 

Otherwise reading the whole lot in and selecting what you want seems advised. I realise that there may be memory issues. 

A concrete example showing what you mean would help (me) greatly.

I want to read in data from the National Education Longitudinal Study,
which is in ASCII format with multiple blocks of numbers rather than
one. I want to tell Stata to look for a specific column in a specific
block, the first of which is not hard but the second I cannot figure
out. For example, how should I amend a dictionary of the form

dictionary using 03955-0001-Data.txt
_column(8) float f4univ1 %4f "Sample member status in all five waves"

to tell Stata to look for f4univ1 in _column(8) of block 1 out of 15?
