Help with diagnosing ASM ERROR 113

I have used a copy of proton plus that uses the dongle for many years and because the dongle is starting to be a bit iffy I purchased this updated version via Les.
I have a program from the old version which controls a observatory dome and have copied the .Bas file into the new proton version. I had to make a few changes to get it to (try to) compile ok but am stuck with trying to figure out this error message

ASM ERROR:Error[113] c:\PROGRAM FILES (X86)\PROTONIDE\PICBASIC_PROGRAMS\A.S 1173: Symbol not previously defined (RSIN)

A typical line of code is  RsIn Dec Domerate
The program compiles and runs fine on the old version of Proton Plus. I have tried both copy and paste the .Bas file and have retyped it in from scratch and no joy

I also typed in a simple test program using the syntax and it compiles ok even though I am using exactly the same syntax as used in the copy and pasted listing.

Any help most appreciated


Without the whole code it would be pretty difficult to answer here.



I have just spotted that this post is in Forum rules so if the moderators could move it that would be great

First off there are a loot of variables not declared, I has a guess and added
Dim domecount As Word
Dim yyy As Word
Dim y As Word
Dim domerate As Word

Then this RsIn Dec yyy should be yyy = RsIn

Looks like y should be a string.



Only some of the code was included
Looking at the assembler it makes reference to RSIN (in capitals) which matches the error output but typing in RSIN auto changes to RsIn

According to the online manual the syntax looks to be correct. Also I have created a small test program which compiles and runs ok. see below

I have also just spotted that its reporting (in addition to the 113 error) a compilation error
Ln 281:col 89

line 281 is the ,============================================================== just after the GoTo manloop. Col 89 is after the last =
Its commented out so the compiler should not be doing anything with it.

Its not reporting its an error just where the cursor is. Sorry about that. I put a rubbish line of code in and it found it ok


It seems to depend which family you compile for. I found that when compiling for a base 16F device (device=16F877A), it does not like the syntax:

RsIn Dec yyy

However, it will accept
RsIn {continuex},Dec yyy

As a simple check, if you change the device to 'device=16F18323' or 'device=18F25K20' it compiles ok using either syntax.

test code:
Device=16F877A           ' fails to compile ... ASM ERROR symbol not previously defined
'device=16F18323         ' compiles ok
'device=18F25K20         ' compiles ok

Dim y As Byte

y = 0
RsOut "  ",011,013

' check three different forms of RSIN

RsIn Dec y

RsIn {continuex},Dec y



I was just preparing the latest update when I saw this thread, so "in the nick of time". :-)

I'll get into the compiler this afternoon and find out why it produces the error only with standard 14-bit core devices. It works as it should with enhanced 14-bit core and 18F devices, so it is a puzzler (for now) because they all share the same Rsin parser function. With a complex mechanism such as a compiler for multiple devices, it always amazes me that something in a function far removed can effect something else that should have no reference to it. You would think after 20 years of creating and maintaining the compiler, I would have gotten used to that scenario, but it still puzzles me sometimes. So once an anomaly has been corrected, I always go through the code to satisfy myself as to why it happened in the first place, and sometimes, it is a fault of the C++ compiler and not a fault of mine. :-)


The RSin anomaly with standard 14-bit core devices, is now corrected and the free "corrections update" is available from here:

Positron Corrections Update -


Thanks to all for correcting this. It compiles my observatory software without errors.
