ReadLn procedure
Read from a text file into variable and goto next line.
Declaration
procedure ReadLn(var F: Text; Args: Arguments)Description
Read reads one or more values from a file
F, and stores the
result in
V1,
V2, etc. After that it goes to the next line in
the file. The end of the line is marked by any of the supported line ending styles,
independent of the platform on which the code is running (supported line
ending styles are CRLF, LF or CR). The end-of-line marker is
not considered part of the line and is ignored.
If no file F is specified, then standard input is read.
The variables V1, V2 etc. must be of type Char, Integer,
Real, String or PChar.
For an example, see Read.
Errors
If no data is available, empty values are returned (0 for ordinal values, empty strings for string values)
