@FILEREAD[n[,length]] : Reads data from the file whose handle is n. Returns the string **EOF** if you attempt to read past the end of the file. If length is not specified, @FILEREAD will read until the next CR or LF (end of line) character. If length is specified, @FILEREAD will read length bytes regardless of any end of line characters.


Numeric input may be entered in either decimal format (a sequence of 0-9 digits) or in hexadecimal format ("0x" followed by a sequence of 0-F hex digits).


This function should only be used with file handles returned by @FILEOPEN. If you use it with any other number you may damage other files opened by TCC (or by the program which started TCC).


Beware of characters with special meaning to Take Command, such as redirection and piping symbols, within the file. Use SETDOS /X with appropriate codes as needed.




set h=%@fileopen["d:\path\myfile.txt",r]

echo reading %@fileread[%h,32]

echo closing handle #%h: %@fileclose[%h]
