Constant values can be in four different formats. Table E.10 lists the different formats and the modi ers to indicate to the PICBASIC compiler which data type is being speci ed. In Table E.10, note that only an ASCII byte can be passed within double quotes. Some instructions (described below) can be de ned with strings of characters that are enclosed within double quotes. The de ne statement is used to change constants given defaults within the PIC microcontroller when a PICBASIC-compiled application is running. The format is

The labels, their default values, and their values are listed in Table E.11. The OSC de ne should be speci ed if serial I/O is going to be implemented in the PIC microcontroller. This value is used by the compiler to calculate the time delays necessary for each bit. Assembly language can be inserted at any point within a PICBASIC application. Single instructions can be inserted simply by starting the line with an @ character:

Note that labels inside the assembler statements do not have a colon at the end of the string and that traditional assembly-language comment indicator (the semicolon) is used. Implementing interrupt handlers in PICBASIC can be done in one of two ways. The simplest way of implementing it is to use the ON INTERRUPT GOTO Label statement. Using this statement, anytime an interrupt request is received, the Label speci ed in the ON INTERRUPT statement will be executed until there is a resume instruction that returns from an interrupt. Using this type of interrupt handler, straight PICBASIC statements can be used and assembly-language statements avoided. The basic operation looks like this:
: ON INTERRUPT GOTO IntHandler : IntHandler: disable : enable requests resume Turn off interrupt and debug requests Process Interrupt Enable other Interrupts and debug Return to the executing code
The problem with this method is that the interrupt handler is executed once the current PICBASIC instruction has completed. If a very long PICBASIC instruction is being executed (say, a string serial send), then the interrupt will not be serviced in a timely manner. The best way to handle an interrupt is to add the interrupt handler as an assemblylanguage routine. To reference the interrupt handler, the de ne INTHAND Label instruction is used to identify the label where the assembly-language code is listed. The interrupt handler will be moved to start at address 0x004 in mid-range devices. A code template for generic mid-range PIC microcontroller interrupt handlers is
