PV‑WAVE has flags for Windows and UNIX that can be used with the “wave” command for setting initial values for the number of local variables and for the code size of a WAVE session.

wave -lv number—Sets the initial number of local variables to number.

wave -cs number—Sets the initial size of the code area to number of bytes.

The corresponding environment variables for Windows and UNIX are WAVE_INIT_LVARS and WAVE_INIT_CODESIZE.
