Write formatted output to a file.

Syntax

fprintf(file_handle, format [, expr [,...] ] )

Discussion

Use the fprintf function to write formatted output to a file.  The fprintf function is similar to the C-language fprintf routine.  (See printf for more information.)

Example

Command input:

define ord4 file1
file1 = fopen("test.dat", "w")
define nstring myStr = "this is a test"
define ord4 myNum = 1234
define char myChar = 'A'
fprintf(file1, "%s %d %c", myStr, myNum, myChar)
fclose(file1)
