 Posted: Sat Dec 24, 2005 4:30 am Post subject: Basic compiler bugged in 2.0.1 ? |
 |
|
Hi all,
I have recently downloaded the official OpenOffice.org 2.0.1 (build 8990).
I installed it on my Win XP Home computer (complete install, after deleting old 1.9 and without data from 1.1).
Then I re-installed Xray and Multipages add-ons. Problem : there is a syntax error in both add-ons 
After investigation, I found two problems related with the continuation character in Basic (underscore character). In the following lines the _ character must be the last character of the line.
| Code: | Sub Main
' comment ending with _
End Sub |
This code displays syntax error : Statement block still open: End Sub missing.
If you suppress the trailing _ the error disappears.
Obviously the comment part of the line was interpreted. 
| Code: | Sub Main
const a = "1234567890" & _
"1234567890" & _
"1234567890" & _
"1234567890" & _
"1234567890" & _
"1234567890" & _
"1234567890" & _
"1234567890"
End Sub |
Here again there is a syntax error. If you suppress one character in any one of the strings, the error disappears.
The compiler does not like strings of 80 characters or more, if they are defined with continuation lines.
Do you also get these errors? If so, this 2.0.1 is nearly unusable for Basic macros.

This does throw an error as does the larger piece of code you posted:
| Code: | Sub Main
' comment ending with _
End Sub |
These do not, however, in the last one Xray reports "a" as being Empty. Xray reports "a" correctly in 1.1.5.
| Code: | Sub Main
' comment ending with_
End Sub |
| Code: | Sub Main
' comment ending with _
a = 1
End Sub |
| Code: | Sub Main
' comment ending with _
a = 1
Xray a
End Sub |

Haven't tried all the test yet, but this seems a little different.
It appears that the problem is with constants of 80 characters. The continuation doesn't matter.
no error
| Code: |
sub strLength
dim a as string
a = "1234567890" & "1234567890" & "1234567890" & "1234567890" & "1234567890" & "1234567890" & "1234567890" & "1234567890"
print a
end sub
|
error
| Code: |
sub strLength
const a = "1234567890" & "1234567890" & "1234567890" & "1234567890" & "1234567890" & "1234567890" & "1234567890" & "1234567890"
print a
end sub
|
Using the continuatoin character in either scenario gives the same results.
EDIT:
OK, all the tests you showed for the continuation character and comments are working just the same for me..But I am also on WinXP..so hopefully a Linux person will check in also.

I checked the code using OpenOffice.org 2.0.1 (Linux). My results are the same as Drew Jensen's. Constants show an error when the string length limit is exceeded. |

OK, the constant bug is related only to the concatenation character ( & or + )
Simplest example, adding a null string | Code: | Sub Main
const a = "12345678901234567890123456789012345678901234567890123456789012345678901234567890" & ""
print a
End Sub |
If you suppress one character the syntax error disappears.
If you suppress the & "" the syntax error disappears.
If you construct the string with concatenation of substrings on several lines you get a syntax error for more than 79 characters in total.
So now we have two different bugs:
- comment lines ending with the continuation character
- long string constants created with concatenation
any more bugs around ? |

The bug "continuation character in comment" produces an error with Xray 5.1 when you are trying to display the API documentation.
There is a compilation error in module Mod4, line 82. | Code: | | if alpha = -1 then alpha = 27 ' name begins with _ |
To suppress the error, suppress the comment or change it like this | Code: | | if alpha = -1 then alpha = 27 ' name begins with _ character |
In fact at runtime the error appears in the module _main because the mod4 module was not correctly compiled.
This is a typical example of a correct macro which cannot run on OOo 2.0.1. |
