Just wondering how do you store on the PIC 16F877? I have on Excel look up table and I want to store it on the PIC. Then I want the user to enter a value on a GUI which will be found on Excel and used as the delay value in my project.
Any ideas?? or does any have any nice GUI's I could look at.

I'm not very sure what you are asking?, if it's how to implement a lookup table on a PIC it's a common technique involving adding an index value to PCL, and a table of RETLW - there's an application note at MicroChip. You can use the same technique for a jump table, replacing RETLW with GOTO.
The main problem with this is you can't cross a 256 byte boundary, unless you take precautions - if you search this site there are details posted previously.
