RetroBASIC v1.7.0
RetroBASIC v1.7.0 adds initial working support for string-slicing dialects where array-like syntax applied string variables is not an array but a slice. This includes HP TimeShare BASIC, Atari BASIC, and others. This was tested using letter.hpb from the 1975 version of What To Do After You Hit Return, which is included in this release. To run HP code, use the -s switch on the command line.
v1.7.0 also adds a number of missing string comparison operations, whereas it previously only supported = and <>.
