managing lists and append to file

[piotto]

hi all,

say for instance i have a list of 100 tickers.
say i want to apply on them my favourite "oracle" system.

is it possible to automatically run "oracle" onto the 100 tickers and append every last signal (buy/sell/out) to a .txt list?

basically the "append to file" command in tradestation.

can you help me with that?
thanks much and sorry for my ignorance, i'm a beginner with efs.
