Help with programming

[wowy7]

i fixed some of the code but it still isn’t working

main
T_IR var word
pan_left var word
pan_right var word
R_IR var word


pan_left = servo p15,1500
pan_right = servo p4,-1500
mid var word
mid = servo p4,0




if R_IR<100 then pan_left *R_IR
endif

if R_IR>100 then pan_right *R_IR
endif

if R-IR =100 then mid *R_IR
endif
goto main

and i use the “main” command all the time
and i even tried using a different program with that, so whats wrong?

Okay… As I said, I’m not completely dissecting your code - just tossing out some ideas. As I don’t currently have access to my hardware, or the specific sensor that you’re trying to work with, I won’t be able to do much with it anyway.

Earlier, you quoted the error message you were receiving:

Compiling... C:\DOCUMENTS AND SETTINGS\BRANDON\MY DOCUMENTS\BASIC.BAS Error: FILE C:\DOCUMENTS AND SETTINGS\BRANDON\MY DOCUMENTS\BASIC.BAS(LINE 8) : [TOKEN P4] : Unexpected token type Errors Detected One of the more useful aspects of these errors is that it tells you where it is seeing the error. Pay particular attention to the line that says:

Error: FILE C:\DOCUMENTS AND SETTINGS\BRANDON\MY DOCUMENTS\BASIC.BAS**[size=150](LINE 8)[/size]** : [TOKEN P4] : Unexpected token type(Emphasis added)

This is telling you that it has found an error in your code, on line 8 of the program as it appears in your compiler window. Move the cursor down to line number 8, and take a good look at what you have there.

Is there an error in your syntax? The syntax guide - downloadable from the website of the microcontroller’s manufacturer - will list the arguments and variables that the commands will be expecting.
Are you referring to a variable that hasn’t been properly declared?
Did you make a typo that is resulting in the error?

In the code that you provided, assuming that “Main” is on line 1, then line 8 would be the one that reads:

pan_left = servo p4,1500

The IDE looks like it’s telling you that it’s finding something unusual in your use of “P4” in that situation.

In referring to the hyphen and underscore earlier, I was referring to your code on line number 24 as listed, assuming Main falls on line number one. Earlier in your program, you define a word variable called R_IR, with an underscore. On line number 24, you use “R-IR”, which it will not recognize as being the same thing. Your IDE didn’t say anything to you about it because it kicked an error back on line 8, and didn’t make it that far. There may be other syntax, logic, or structural errors as well - that’s just the one that jumped out at me upon a cursory inspection.

Declaration:

R_IR var word

Implementation:

if ((R-IR =100) then mid *R_IR

yea id guess that its not going to work anyway so
im going to get about two GP2D12 sensors
so i guess the sensor that i have is useless by now

well thats all 8)
