New releases of LIFUTILS, pyILPER and asm71

[rprosperi]

Test driving the new releases of pyILPER and LIFUTILS was smooth and interesting. The HP75 TEXT file handling enhancements worked well, making the process of moving text HP75 BASIC files back and forth between the 75 and the PC (for editing) easy and quick.

The new ability to view the keywords in a 75 LEX file is also quite handy. If you plan to enhance this area in the future it would be nice to also display the parameters and types needed by the function keywords similar to those shown by the HELP LEX file.

Very nice enhancement Joachim, thanks for these improvements!
