Error[113] D:\TP2_ASM\TP2.ASM 19 : Symbol not previously defined (*)

[aydi]

good morning,

i have two errors when i try to compile the following program.

please can any one help me to solve this PB.

thanks an advance.

message error:

I assume th problem is the lines

movlw 0x23*
movlw 0x14*

What are the asterisks for? Try removing them.

Keith.

 

[aydi]

yes exactly the pb is there but why?

why if we change them for example with movlw 20 (0x14) it works?

 

[keith1200rs]

What is "pb"?

Why would you expect it to work with random, incorrect characters added to the statements?

Keith.

 

[aydi]

movlw 0x14 (hexa. representation) it should work normaly.

why for example if you write (movlw 0xff) it works.

my question is clear why it does not accept hexadecimal representation.

 

[betwixt]

It will work in decimal or hexadecimal, the problem you highlighted in red is caused by the '*' in the asm code. That symbol is not part of the PIC istruction set so it was flagged as an error.
change it to 'movlw 0x23' or 'movlw .35' and it will work.

The other messages are warnings, you missed out the destination in both the 'decfsz' instructions. Warning 302 is just to alert you to check you have used the correct banks, it does not stop the file being assembled. If you are sure the banks are correct, you can stop the warning by adding 'errorlevel -302' at the top of your code.

Make sure you use zero and not the letter 'O' at the start of hexadecimal numbers.

Your question is far from clear!

You can use

movlw 20
movlw 0x14

but NOT movlw 0x14*

Why add the asterisk? You can use an asterisk when doing certain TBLRD and TBLWT instructions, that is all.

the * doesn't appeared when i use mplab.

it apperared when you copy it from mplab to the forum.

thanks.

i solve the pb.

sorry i want to say it's appeared when i copy my program to the forum(typo).
