[Description]
Checks for a system-reserved variable name.

[Explanation]
SymSysVar checks if a variable pointed to by <I>VarName</I> (an ordinary C
string) is a system-reserved variable stored in the symbol table (in the main
folder). It returns the same values as
<A HREF="$$LINK(CheckSysFunc)">CheckSysFunc</A>. Additionally, it returns
<A HREF="$$LINK(ExtendedSysTypes)">R_SYSVAR</A> if the variable name is
"SysData" or "RegCoef". In fact, this function calls
<A HREF="$$LINK(CheckSysFunc)">CheckSysFunc</A> with additional checks for
"SysData" and "RegCoef".
