The tokenized forms are also used within project files to store file information. This simplifies the

backup and transfer of projects to another computer, since file information is interpreted locally instead

of by using absolute paths.

8.3 Labels instead of Addresses

Label names, as listed in a loaded symbol table, or as found in the register information file, may be used

wherever an address is expected. Label names are partially case sensitive.

Xplor8 looks up symbol names in an ordered fashion: first it checks for a name with exactly the case

entered. If there is no case-sensitive match, then a case-insensitive search is done. If a single match is

found, then this is used; however, if more than one label is found which matches the spelling (but not

the case) of the label supplied, then the first matching spelling is used.

For example, suppose the following symbol file is loaded:

Main 8026

Dly1 802c

LongDly 8033

MAIN 8039

TestLoc 8042

• Entering 'Dly1' will find $802C

• 'DLY1' will find $802C (no other label has the spelling 'D L Y 1')

• 'Main' will uniquely find the value $8026.

• 'MAIN' will uniquely find $8039

• 'MaiN' will find $8026 being the first instance of 'M A I N' in the list

The command:

L Main LongDly

would be the same as:

L 8026 8033

And the command:

F 8050 8050 TestLoc

would fill the two bytes at $8050/1 with the address of TestLoc ($8042)

All the control registers on an 'E' series chip could be listed by typing:

L PortA Config

this is equivalent to:

L 1000 103F (provided the registers are in their default location)

1 2 ... 37 38 39 40 41 42 43 44 45 46 47 ... 99 100
