this are the code

I ran your code, it looks like the file SDFS3 that cam with the download, and it compiled fine.
The only way I can reproduce your error is to try compiling SDFS.

Using PBPL
target is 18F4550

What other errors are you getting?

[NURULHAIZA]

i don't have the PBPL box in my widow..here are the picture..

[NURULHAIZA]

i have use the new version of MCS..i'm using the 3.0.0.5 version. but i'm facing a new problem which is this " The Microchip assembler (MPSM) only allows up to 62 character to be used for path and filename".....

[HenrikOlsson]

Hi,
Then simply change the location (path) and/or filename of your sourcefile so that the complete path and filename is less than 62 characters - simple as that.

As an example, having your source files in project folder in a PIC folder in MyDocuments is bad as the full path might be:
C:\Documents and Settings\Nurulhaiza\My Documents\PIC\MySDFSProject\Source.pbp which is 78 characters. Moving it to C:\PIC\MySDFSProject\Source.pbp will work as the path and filename now is 31 characters.
