Thanks hippo, I understand the LAST function, but key is "WHERE" to insert this idea. Tried immediately after updating the line counter, but still reads whole file. Sorry to be so inept. | [reply] |

last if $line_count > 29;
Put it right after $line_count++;. You may Read the whole file via get, but then only PROCESS the beginning | [reply]
[d/l]
[select] |

Thanks huck, I now understand the difference between read and process. Any thoughts on how I could approach the idea of "reading" the web page line by line? Thanks for your patience.

Apologies. huck is correct, it's obviously the $line_count variable which should be tested rather than $line in this instance.
This will only stop it processing the whole file. If you don't want to download the whole file then that's a different matter entirely and would require use of a technique such as HTTP Ranges.

Hi Hippo, your answer above states "If you don't want to download the whole file then that's a different matter entirely and would require use of a technique such as HTTP Ranges." I've tried to Google HTTP ranges but no luck. Any ideas where I get a sense of what have in mind? Nothing else seems to work (just trying to nab the few lines from web pages). Thanks!
