/* B B A N - A Better Banner Program - Apr84 IBM-PC version */ /* The vax version will not work directly on the PC, because the ** UNIX shell metacharacter interpretation caused strings like ** 'one two three' to be passed as a single command line arg, while ** under DOS, it becomes three: "'one", "two", and "three'" ** So, we need a scheme for embedding spaces in arguments. ** One: choose some other character like underscore '_' and after ** command line argument passing, translate it into a space. ** Two: alter the program logic to treat single and double ** quotes as delimiters, and keep concatenating DOS-passed arguments ** until the closing delimiter is detected. ** Two is more elegant, but One is easier. */ #include #if defined(__STDC__) || defined(__cplusplus) # define P_(s) s
