Read from a text file into variable and goto next line
Source position: line 0
procedure ReadLn( |
var F: Text; |
Args: Arguments |
); |
Args: Arguments |
); |
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 the LineEnding character sequence (which is platform dependent). 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.
If no data is available, a run-time error is generated. This behavior can be controlled with the \var{\{\$i\}} compiler switch.
