fwrite_stringfwrite_stringFwriteStringfwrite_stringFwriteStringFwriteString — Write values in a file.

Signature

fwrite_string( : : FileHandle, String : )

Description

The operator fwrite_stringfwrite_stringFwriteStringfwrite_stringFwriteStringFwriteString puts out a string or numbers on the output file defined by the handle FileHandleFileHandleFileHandleFileHandleFileHandlefileHandle. The output file must be opened in ASCII format by the operator open_fileopen_fileOpenFileopen_fileOpenFileOpenFile. The values to be put out on the file are set in the parameter StringStringStringStringStringstringVal.

The call set_system(::'flush_file', <boolean-value>:)set_system("flush_file", <boolean-value>)SetSystem("flush_file", <boolean-value>)set_system("flush_file", <boolean-value>)SetSystem("flush_file", <boolean-value>)SetSystem("flush_file", <boolean-value>) determines whether the output characters are put out directly on the output medium. If the value 'flush_file'"flush_file""flush_file""flush_file""flush_file""flush_file" is set to 'false'"false""false""false""false""false", the characters (especially in case of screen output) show up only after the operator fnew_linefnew_lineFnewLinefnew_lineFnewLineFnewLine 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.

Parallelization

Example (HDevelop)

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

Example (C)

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

/* Tupel Version */
  int  i;
  double d;
  Htuple Tuple ;

  create_tuple(&Tuple,4) ;
  i = 5 ;
  d = 10.0 ;
  set_s(Tuple,"text with numbers: ",0) ;
  set_i(Tuple,i,1) ;
  set_s(Tuple," and ",2) ;
  set_d(Tuple,d,3) ;
