The Pascal Macro Compiler has a set of macros that will pack character strings without any wasted space between them The macros can be downloaded directly from the webpage http://www.contestcen.com/paskey.htm which has both the source code and a detailed description.

How can a preprocessor (macro compiler) help here, when it runs at compile time, while time question was clearly about runtime storing of strings (mentioning New and block moves etc.)?
