[RPL/2] Lot RPL2, Vol 39, Parution 2

[Woody Jeon]

Hello,

I'm grad to hear from you :)

I checked the source code as you mentioned

Comparing two archives with sha256 checksum gives;

                 
70b02347723e463c381a315a3695681f0addb831bb4ba009dc4ec8ea3bf235f6  
rpl-4.0.0.prerelease.2.tar.bz2
                 
d7c674f8c45da752531d4250e781e6eb633e09865d572fbf1144c20cbd419827  
rpl-4.0.0.prerelease.2.tar.bz2.Oct1

It's different!

    I've looked into the source code(src/encart.c), and found that  
XtDestroyWidget() functions were missing in my archive,

    which I downloaded the source (rpl-4.0.0.prerelease.2.tar.bz2) from 
the official RPL/2 web directly before Oct. 1

             XtDestroyWidget(pixmap);
             XtDestroyWidget(cadre);
             XtDestroyWidget(form);
             XtDestroyWidget(popup);
             XtDestroyWidget(objet_principal);


I don't understand why this happened ;-)

I have some suggestions regarding this issue,

It's a good idea to give checksums(i.e, md5) on the official web site, and


Another suggestion is;

    it's also useful to offer some links to access HP RPL document

    For your convenience,

              
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00554621/c00554621.pdf

        or, RPL wiki page

              http://en.wikipedia.org/wiki/RPL_(programming_language)

Thanks a million for your help, and

I cannot help but appreciate your a great deal of efforts into RPL/2

Please keep your good work!


Best regards,

Woody Jeon
