Dave, i understand what you are trying to say. But, in microengineering website, there got a resources/information about using pic basic compiler. inside there, got a statement as below,try to read it.
--------------------------------------------------------
A part of statement:
PICBASIC™ Compiler programs may be run at clock frequencies other than 4MHz if you pay attention to what happens to the time dependent instructions. If you wish to run the serial bus at 19,200 as described above, you would simply clock the PICmicro MCU with an 8MHz crystal rather than a 4MHz crystal. This, in effect, makes everything run twice as fast, including the SERIN and SEROUT commands. If you tell SERIN or SEROUT to run at 9600 baud, the doubling of the crystal speed will double the actual baud rate to 19,200 baud.

However, keep in mind commands such as PAUSE and SOUND will also run twice as fast. The Pause 1000 mentioned above would only wait .5 seconds with an 8MHz crystal before allowing program execution to continue.
--------------------------------------------------------
This is why i'm trying to ask the question about PAUSE/PAUSEUS command.
