The Question is:

 
How  To  append NULL Character (Ascii 0) to Line Feed character (Ascii 10)
in
a file?
 
 
Hello ,
 I have a file in which There is Line Feed Character Line Feed (Ascii 10)
followed by NULL Character ( Ascii 0) .   NULL character if  comes  in next
line after the LF character. Now Problem is because
some requiremet I want to put NULL character ( ASCII 0) immediately
after LF character.  ( It should come in same line ).
 
 I write C program for this. But it is always moving to next line.
 
 Thx  a lot in advance for any advise on this .
 
 Thx & Regards

The Answer is :

 
  The OpenVMS Wizard expects this is a C programming question, as C
  designates the null character for special handling -- the null
  character is a string terminator in C.  OpenVMS, RMS, and the file
  system -- as differentiated from C and the C run-time library -- do
  not particularly have special handling for the null.
 
  C can deal with null characters quite nicely, though many of the
  C functions -- such as str* functions -- will terminate processing
  of any strings when the first null is reached.  Functions such as
  the C mem* functions, or OpenVMS RTL or various system service calls,
  would typically be used to process strings containing nulls.
 
  If you wish to pursue this question via Ask The Wizard, the OpenVMS
  Wizard will require a full C code example of the particular problem
  being reported, as well as the particular file organization (such
  as the output from DIRECTORY/FULL or otherwise) of the file involved.
