fwrite_string

fwrite_string ( : : FileHandle, String : )

Write values in a text file.

The operator fwrite_string puts out a string or numbers on the output file. The operator open_file opens a file. The call set_system(::'flush_file', <boolean-value>:) determines whether the output characters are put out directly on the output medium. If the value 'flush_file' is set to 'false' the characters (especially in case of screen output) show up only after the operator fnew_line is called.

Strings as well as whole numbers and floating point numbers can be used as arguments. If more than one value serves as input the values are put out consecutively without blanks.

Parameters

`FileHandle` (input_control)	file `->` integer
File handle.

`String` (input_control)	string(-array) `->` string / integer / real
Values to be put out on the text file.
Default value: 'hallo'

Example

fwrite_string(FileHandle,['text with numbers:',5,' and ',1.0]).
/* results in the following output:       */
/*    'text with numbers:5 and 1.00000'   */

Result

If the writing procedure was carried out successfully the operator fwrite_string returns the value 2 (H_MSG_TRUE). Otherwise an exception handling is raised.
