This variable sets the number of indexed block buffers to allocate. These buffers are used to improve the performance of indexed files. Each buffer is 512 bytes plus some overhead. Increasing the number of buffers can improve file performance. Decreasing the number conserves memory. The value of V_BUFFERS has no effect on versions of ACUCOBOL-GT that do not use Vision files. The value of V_BUFFERS can range from zero (no buffering) to 2097152. The default value is 64.
