How to write a NULL to a file.
You can use the NULL keyword to output null characters (\0)
with PUT CONTROL.
Example :
OUTPUT TO testfile.
PUT CONTROL NULL.
To write multiple NULLs :
PUT CONTROL NULL(n).
n = number of nulls to be written.
To embed NULLs in between data :
PUT "This is to test".
PUT CONTROL NULL.
PUT "the null character" .
The output will be :
This is to test the null character.
The \0 is not readable; however it can be looked at on the UNIX
systems with octal dump : od -c <file>.
REFERENCES TO WRITTEN DOCUMENTATION
