Hi E,
Thanks.
Can I post the whole program, to see if it configures at your end?
C

 

Hi E,
I didn't write this program (much beyond my skills), and it is sent to me as TXT and CODE, the TXT doesn't compile these errors, but the CODE compiles these errors. It is not being written in Oshonsoft, which may be a clue.

Hi C,

It appears to accept the Dim's , but the rest of the Code reports endless errors.

It is not compatible with OSH.?

He's an Ozzie, and it is written in C. He sent it to an Arduino, and it compiled.

Hi C,
Arduino is 'brand' of the 'C' language.

The Arduino IDE is a free download and use program, why don't you download it and install.?

There are many features of the Arduino series that you may find useful and easy to use on parts of your project.

Hi E,
I have Arduino, and have copied and pasted downloaded programs onto them, but have never got into programming them. (For me it's just too difficult)
Thanks.

Hi E,
I've laundered it! comment all out, copy and paste to a txt file, re-introduce it to OSH, and uncomment.
It compiles down much better.
What do you think?

Hi,
Does anyone know whatis causing this error, please?
Camerart

Looking at the error, the text may not have real < cr> or <lf> characters but some type of Linux or multilingual characters. I suspect you just copy/paste the original code. Hence the compiler sees three lines as one statement, which it cannot compile.

 

Hi,
This CODE is now compiling in Osh, but not working, and shows this error.

Eric, "While 1" compiles ok in PIC18 Simulator IDE V4.38 (my own test program)
Osh creates a temporary bit storage location when one views the ASM code generated (snippet below):

Perhaps I should.
