If I have code such as: set message=The %ReleaseTitle% is now official.%@char[13 10 13 10]The master image is located at:%@char[13 10 9]%%ReleasedMediaFolder%%@char[13 10]The source code for this release will be archived to:%@char[13 10 9]%%ArchiveFolder. I seem to be getting a failure to always interpret the @char functions! I thought - that if I have a set variable I can use a single % to indicate it, and optionally I can end it with a surrounding %, such as: %variable %variable% Either is correct, so long as the interpreter can distinguish the end of the variable. If it cannot, the second % is needed to help it out, such as: %FirstName %LastName %FirstName%%LastName% Because the whitespace makes it clear that %FristName is ending, no surrounding % is needed in the first example, but it is needed in the second because otherwise it would read: %FirstNameLastName Which would not expand properly. I thought that the same rules apply for %@functions. I thought that this worked for years? But now I'm finding that %var%%@char[13 10] only sometimes works, and other times fails... What is the correct rule? Is this a bug in my version of TCC? Or do I just have the rules all wrong?
