The highest set SVar ID.

## ตัวอย่าง

```c
// Store the upper index in the variable 'SVarUpperIndex' + 1
new sVarUpperIndex = GetSVarsUpperIndex() + 1;

// This sVarCount variable will store how many sVars are set as we count them.
new sVarCount;

for (new i = 0; i != sVarUpperIndex; i++) // Loop through all sVar IDs under the upper index
{
    // At first, we need to get SVar name
    new sVarName[128];
    GetSVarNameAtIndex(i, sVarName, sizeof(sVarName));
    // If the var is set (type not 0), increment sVarCount.
    if (GetSVarType(sVarName) != 0)
    {
        sVarCount ++;
    }
}

new szString[66];
printf("There are %i server-variables set. Upper index (highest ID): %i.", sVarCount, SVarUpperIndex - 1);
```
