Collection of advanced programming tips for the Timex/Sinclair 2068, compiled from the TIMELINZ newsletter. Includes: POKEing RAMTOP without destroying variables; calculating program elapsed time in seconds; inverting the screen display; determining if a number is even or odd (noting that the standard (-1)^N method fails on the 2068); a two-part machine code routine to save/recall a screen to address 57000; moving the line editor to the top of screen; and an alternate CODE load method for stubborn programs.
