Returns a series of bytes from a file or a communication port opened with a low-level file function until it encounters a carriage return.
Syntax
FGETS(nFileHandle [, nBytes])
Returns
Character
Arguments
nFileHandle
Specifies the numeric file handle of the file or communication port from which FGETS( ) returns data.
nBytes
Specifies the number of bytes FGETS( ) returns. FGETS( ) returns nBytes bytes unless a carriage return is encountered first. FGETS( ) returns data between the starting file-pointer position and the carriage return if a carriage return is encountered within nBytes bytes.
If you omit nBytes, FGETS( ) returns a maximum of 254 bytes by default.
Remarks
You can read a file line by line by issuing a series of FGETS( ).
FGETS( ) returns a series of bytes as a character string. Data is returned starting from the current file's pointer position and continuing until a carriage return is encountered. The file pointer is then positioned on the byte immediately following the carriage return. The carriage return isn't returned as part of the string, and line feeds are discarded.
