This file is the documentation for TIMEZO.BAS. The program calculates the current time and day in selected cities. The program is written is standard Microsoft Basic, with screen layouts designed for 8x40 or 8x80. With changes to the date and time instructions, this should run on most machines. The version uploaded is ready-to-run on a Tandy model 100, Nec 8201 or Ollivetti M10. To run on a Epson PX-8, delete line 1300, and remove the first apostrophe from lines 50 and 1280. When you are prompted for a city name by the program, upper and lower case are accepted, and a short name is sufficient (e.g. LON for London). Add or delete any cities you like by modifying lines 10000+. Remember to also alter line 16000, the city count. Each data line should contain the name (in quotes), comma, the time difference from GMT/UTC in decimal hours, comma, DST details: "?" if you're not sure, " " if there is never DST, or start and finish dates for DST in the form "mmdd- mmdd". Remember to SAVE to the program when you've changed it. This is a preliminary test version, please send you comments, suggestions and bug reports to Robert Hoare, CIS 74116,537 or Source BCX713.
