Hello,

sorry, I don't understand. Can you show some code that triggers the problem?

  Hello,
  
  Here is the entire comment block. The first line that fails is in bold red:
  
  "/'
  
  Function: heartBeat
  
  Purpose:
  
  Continuously poll V-MAC.
  
  Used in conjunction with <getbyteatport> to determine if V-MAC is online.</getbyteatport>
  
  <ping></ping> is used just once prior to conMain.
  
  Returns:
  
  Enum - vrcHeartBeat if successful.
  
  Const - VV_NOT_READY if number of bytes at port <> 1.
  
  Const - VV_FAIL on any other error.
  
  Error Handler:
  
  heartBeatError - <reef></reef>
  
  Called By:
  
  frmMain - <commain></commain>
  
  Calls:

  Bit Assignments:
  
  - < = > send keypad programming status To PC - V-MAC returns status Byte - Not echoed by PC - multitasked

  Note 1:
  
  "Packet Numbers" are used for this Command only and are Not otherwise
  
  involved in the Neuron logic.
  
  Note 2:
  
  Transmit and receive have individual packet numbers. Each Time V-MAC
  
  sends Or receives a Neuron packet,
  
  the corresponding packet number Is incremented.

  Upon further review I see it is as likely the "-" after "Enum" that is
  causing the problem.
  
  To solve this issue either of the following will work on my PC:
  
  Single ' before Enum
  
  ' Enum - vrcHeartBeat if successful.
  
  Single ' after Enum
  
  Enum' - vrcHeartBeat if successful.
  
  I hope this is helpful.

Hmm, weird. I can't reproduce the problem. Everything inside the /' ... '/ block comment is ignored here, even if it contains the word Enum...

But, judging from the error message you got, it looks like the commentary starting with the line containing Enum - ... is parsed as code, and not treated as comment. Maybe the comment block is closed too early? (is there a '/ where it shouldn't be?)

  Hi,
  
  Tried a number of variations and always compiles correctly until the single
  quote is removed from in front of Enum then the errors occur as reported
  earlier.

Hmm, that appears to confirm that for some reason the line is not inside the block comment.

I haven't been able to reproduce it so far though. Could you post a .bas file that shows the problem? Thanks.

Unable to reproduce error. Will re-open if example example code can be provided that demonstrates the problem. Tried all -lang dialects on many fbc versions (0.14.0 through 1.06.0).
