You can create/use PersistentVariables as shown below, they will save
data indefinitely until deleted. To save numbers you convert them to a
string first and pass the string to the function,
for example: String = numtostr(Number,1.2);


PersistentPath = "C:\\Program Files\\AmiBroker\\PersistentVariables\\";

function PersistentVarSetText( VarName, String )
        {
        global PersistentPath;
        fh = fopen( PersistentPath+VarName+".pva","w" );
        if( fh )
                {
                fputs( String, fh );
                fclose( fh );
                }
        return fh;
        }

function PersistentVarGetText( VarName )
        {
        global PersistentPath;
        fh = fopen( PersistentPath+VarName+".pva","r" );
        if( fh )
                {
                String = fgets( fh );
                fclose( fh );
                }
        else string = "";
        return String;
        }
