| 19 Once one or more BASIC09 procedures are debugged to the programmer's | |
| 20 satisfaction, they can be "packed" or converted permanently to the | |
| 21 bytecode form. | |
| 22 </para> | |
| 23 <para> | |
| 24 Packed BASIC09 procedures are in fact OS-9 modules, and the OS-9 shell | |
| 25 recognizes them as I-code and passes them off to the virtual machine | |
| 26 emulator RunB for execution. RunB avoids a great deal of the overhead of | |
| 27 the typical interpreted BASICs of the day -- not to mention that one can do | |
| 28 integer calculations where appropriate rather than doing everything in | |
| 29 floating point -- so that BASIC09 programs run very quickly in comparison | |
| 30 with interpreted BASICs. | |
