Read lines in the file (READ)

The READ command reads one or several lines in the specified file and stores the information
read in a STRING type array. In this array, each read line occupies an array element.
Requirement
The currently set protection level must be equal to or greater than the READ right of the file. If
this is not the case, access is denied with an error message (return value of error variable = 13).
Syntax
DEF INT <error>
DEF STRING[<string length>] <result>[<n>,<m>]
READ(<error>,"<file name>",<start line>,<number of lines>,<result>)
