Syltrem gave one suggestion.
Another, which I think works (it works under BASIC+2 anyway) is:

+++
OPEN filename AS FILE n, ORGANIZATION SEQUENTIAL VARIABLE, &
   RECORDTYPE ANY

GET #1
MOVE FROM #1, A$=RECOUNT
+++

that will give you the record in A$. Repeat until EOF.

In general, the answer to the question of how to get data without a MAP 
is the MOVE statement.
