Hello All!

This post is really a newby request for help on how to do
quoting within the MPE command interpreter (CI).

After changing the group/user permissions to include PH (Process
Handling) capability, I can execute programs that are build with
the c89 compiler. Thank you all for your help :-)

However, I have another problem with the c89 compiler. This problem
has to do with the "-D" command line switch that is used to define
symbols ~ it is equivalent to a #define embedded in the code.

Consider the following (fancy) "Hello World" program, that I want
to 'internationalize' by allowing the greeting "Hello" to be changed
at compile time. (e.g. The Australian version should have "G'day")
[OK - its a very bad form of internationalization...]

#include <stdio.h>

int main()
{
        printf(HELLO);
        printf(" world!\n");

        return 0;
}


To build this program, I would like to issue a command like:

c89 -o hello -DHELLO=\"G\'day\" hello.c

Note the use of the backslash (\) to remove the interpretation of the
quote characters by the shell.

This command works in Unix (with gcc), but when I try it on the HP 3000
inside the Posix shell I get an error:

shell/iX> c89 -o hello -DHELLO=\"G\'day\" hello.c
    ccomxl.pub.sys;info="-Ap -DHELLO="G'day" ";parm=7
                                      ^
Encountered an unexpected word. (CIERR 10061)
    ccomxl.pub.sys;info="-Ap -DHELLO="G'day" ";parm=7
    ^
Implied run command failed due to parser error. (CIERR 9057)
c89: warning:  compile of './hello.c' failed
c89: error:  one or more compiles failed; aborted


As can be seen from the error output above c89 is a shell script
front end to the MPE CI compiler. The quoting works within the
context of the shell, but it then breaks down inside the info="..."
parameter passed in MPE.

How can the double quotes inside the MPE info parameter be quoted,
so as to preserve their special meaning?

Any help on this matter is appreciated,
