It would be nice to know what sort of errors you're running into.
You may have a few problems...
you don't check the return value from
a = MemPtrNew(10);
you don't check for (a == NULL) before you
len = StrLen(a);
there are some (non default) compiler settings which make
StrCopy(a,"dinesh");
fail if globals aren't available.
