Each SVar (server-variable) has its own unique identification number for lookup, this function returns the highest ID.


// 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, pVarName, sizeof(pVarName));
// If the var is set (type not 0), increment sVarCount.
if (GetSVarType(pVarName) != 0)
sVarCount ++;
new szString[66];
printf("There are %i server-variables set. Upper index (highest ID): %i.", sVarCount, SVarUpperIndex-1);
