okay, well, you read a file using $read the following are examples:
to read a random line: $read(C:\myfile\ishere\file.txt)
to read a specific line $read(C:\myfile\ishere\file.txt,LINENUMBER)
to search a line for a specific word/phrase: $read(C:\myfile\ishere\file.txt,w,*phrasehere*)
to search for a line that starts with a specific word use: $read(C:\myfile\ishere\file.txt,s, wordhere)
let me know if you need anymore examples.
Eamonn.
