I'm confused about why this code seems to work fine in isolation, but I get an error when I put it all together.
The following snippet prints 'Hello World!' when printed:
| blah |
blah := 'Hello '.
blah, 'World!'.
But the following code block gives me the error Variable or expression expected
| blah |
blah := 'Hello '.
blah, 'World!'.
| blah2 |
blah2 := 'World!'.
blah, blah2.
Could someone explain what's going on here?
variable declarations are only allowed at the beginning of a block or method:
| blah blah2 |
blah := 'Hello '.
blah, 'World!'.
blah2 := 'World!'.
blah, blah2.
