PRGM commands now match the real machines:
• While editing a program, SHIFT+9 opens CLR; 1:Mem inserts ClrMemory (or ClrStat in an SD/REG program)
• SHIFT+MODE+1/2/3 inserts Deg / Rad / Gra
• CLR is also available from the PRGM menus
• ClrMemory clears A–F, X, Y and M; ClrStat clears statistical data
• Restored on both fx-50FH II and fx-3650PII
