<a name="l1"></a><span class=cF0>ZealOS has a string indirection feature implemented with the same hash symbol table entry as </span><span class=cF2>#define</span><span class=cF0> macros, </span><a href="https://zeal-operating-system.github.io/ZealOS/Kernel/KernelA.HH.html#l824"><span class=cF4>HTT_DEFINE_STR</span></a><span class=cF0>.
<a name="l2"></a>Support for string lists is also provided, but it's not very efficient, though, you can make a hash table with a list using </span><span class=cF4>

<a name="l5"></a>If you have an </span><span class=cF2>@</span><span class=cF0> as the first char of a define list entry, it is an alias for the prev entry num.
<a name="l6"></a>
<a name="l7"></a>Each task can load its own Define strings. Remember, when a </span><span class=cF4><u>Hash</u></span><span class=cF0> table is searched for a string, if it is not found, the
<a name="l8"></a>parent task's table is searched.

Set a text entry with a </span><span class=cF2>D=</span><span class=cF0> arg,
