It's the CALL command that I'm talking about.

Please take a look at the URL from IBM.

Can't you not append the NULL (x'00') in the CPP?

Hi folks:

How do you append a hex 00 byte to a text/char command line parameter?


CALL MYLIB/MYPROG PARM('My Text/Char parameter' + X'00)

The latter does not work because the plus sign would obviously be taken
the second parameter and just then the X'00' would be taken as the third
parameter. Of course that is not what I want.

According to IBM, below, it says that I don't need to do that because the
system automatically appends a hex 00 to the text parameter. Please
out this link:


But I wrote a small RPG program to test for a hex 00 byte and it doesn't
really do it.

My test program expects a 64-byte single parameter. Then I call it like

CALL MYLIB/MYPGM('my small text parm')

Then within my program, a test for a hex 00 like:

nullBytePos = %SCAN(X'00': text_param);

And it returns zero. What is wrong then?
