19.4 Write()

This function writes data to the file.

Format: Write(file_handle, value, num_of_bytes)

Parameters:

file_handle "handle" to the file previously opened by OpenFile()

value Data to write

num_of_bytes Optional parameter specifying how many bytes to take from the

value parameter (if omitted, length is calculated automatically

based on the value type)

Remarks:

This function is primarily for binary files. It can be used for text files only if the value parameter is a string of text.

In that case, it is equivalent to the WriteString() function and the num_of_bytes parameter is ignored.

Example:

…

set BinFile = 0;

…

BinFile = OpenFile("C:\\data.bin", 0, _FO_BINARY);

…

# Write a string to the binary file.

Write(BinFile, "All we need is love!!!");

# Write a substring ("All") to the binary file.

Write(BinFile, "All we need is love!!!", 3);

val = 0xBEEF;

Write(BinFile, val); # Writes integer = (EF BE 00 00) to the binary file.

Write(BinFile, val, 2); # Writes WORD = (EF BE) to the binary file.

# Write a byte chain to the binary file.

Write(BinFile, 'AABBCCDDEEFF12345678');

# Write a list of values to the binary file.

Write(BinFile, [ 0xAA, "USB", 12, 0xBEEF ]);

…

CloseFile(BinFile); # Closes the binary file.
