Supposed it will be not required to invoke this function at the
"Slang>" or "M-x" prompt, I would prefer to do it with a namespace
like that:

in cal.sl:
...
static variable configs= struct{
     max_lines,
     ....
     fp_mark_diary_entries
};
....
fp_mark_diary_entries= &mark_diary_entries;
....
runhooks( "cal_init_hook", configs);

in jed.rc:
define calendar_mode_hook( configs)
{
   configs.max_lines= 10;
   ...
   @configs.fp_mark_diary_entries();
}

Beyond that I would consider to avoid the call-back
in the hook function and replace this by a configs
flag variable, on which the function might be called
behind runhooks.
