The following worked fine in 2.0.5.0 and earlier:

Code:

$regfile = "m128def.dat"
$crystal = 16000000
$hwstack = 800                                              '100
$swstack = 500                                              '200
$framesize = 300                                            '600
$Baud = 9600

Dim TestString As String * 10


 Print "VM " + TestString + ",0" + Chr(13) ;

 End
 


Under 2.0.6.0, it reports this error when compiling

Error : 42 Line : 12 Numeric parameter expected ["VM] , in File : C:\MCS Electronics\BASCOM-AVR\testprint.bas
Error : 31 Line : 12 Invalid datatype [[0011] 0[13)]] , in File : C:\MCS Electronics\BASCOM-AVR\testprint.bas

I assume it's the CHr(13) ?

( I see nothing in the history file nor the new HELP file that would explain this change)

There is nothing in the Help file that would suggest the use of a plus sign (at least I can not find any).
If you replace it with a semicolon then it works.
It also works if you use a separate print command for CHR(X).

This change in behaviour may be due to a bug fix related to strings:

History.txt for 2.0.6.0
- using {034} and quotes gave a problem when they were unbalanced.

The correct way to print multiple variables is to use the semicolon. The contatenation (plus sign) seems to give odd results sometimes.

indeed the correct way is to use semicolon, but i changed it so + will work as well. this will keep code compatible.
