The GLOBALBLOCKSUSED parameter displays the number of global variable blocks in use. The global variable database is divided into 256-byte segments. Each global variable and relational table row requires at least one block and may require a number of additional contiguous blocks to hold all of the data. Most of the first block is not used to contain data, but instead contains information associated with the variable (for example, the name of the variable). The value of the GLOBALBLOCKSUSED parameter is greater than or equal to the value of the GLOBALUSED parameter.
