We swear by DDREAD, a utility developed by Fred Knight. Check out

ftp://ftp.rsinc.com/pub/user_contrib/knight/

From the in-line documentation:
; This routine reads data in formatted (or unformatted) rows and
columns.
; The name stands for Data Dump Read. By default, comments are
; skipped and the number of columns is sensed. Many options
; exist, e.g., selecting rows and columns, reading binary data,
; and selecting non-default data type and delimiters.

Cheers,
Liam.
