The Lounge What is on Your Mind? The C64 is back, this time full-sized with a working keyboard for the dedicated retro home-computer Post 303036738 by Neo on Wednesday 10th of July 2019 03:36:53 AM

Yeah, I wrote all my own programs for the C64, in "Commodore Basic" or something like that, as I recall.

All the programs I wrote were related to land surveying, which were all based on geometry and trigonometry, calculating azimuths, distances, grids, grades, fill for construction sites, industrial sites, pipelines and highways (or customer billing / invoicing) and making morning print-outs on a dot-matrix computer.

I can still hear the sound of the dot matrix printer grinding out numbers for the days work as we drank our morning coffee and prepared to load equipment into the truck.

Those were the days ..... long hair down to the middle of our backs, notebooks and pen in hand, making big money as "modern day land surveyors" in a world where computers has not yet "made a splash".

For us, and our customers, the C64, the TRS80, the Amiga and more made us a pile of money, "back in the day".

It was the Dean of Students at Tulane University in New Orleans, many years later, who convinced me to "move on" from my career in land surveying (he said it was best not to work in the day to day weather, but become a EE / computer engineer), enroll in the engineering department and study EE.

At Tulane, we sat in the hall in lines and waited in long queues to use the first Apple IIs, then Mac 128Ks, then Macs 512Ks, the Mac Plus and then the Macintosh SE, for our lab reports and ran Fortran and COBAL programs on VAX.

What a great life and how lucky we were to experience the "dawn of the computer age" in every day life.

XCALEV(1)						      General Commands Manual							 XCALEV(1)

NAME
xcalev - load xcal calendar files with regular dates SYNTAX
xcalev [ -r ][ -x ][ -f file ][ -d dir ][ year ] DESCRIPTION
Xcalev is used to preload the calendar files for the xcal program with regular events in your life. It reads lines from a file (usually called regular stored in your Calendar directory. Each line in the file contains three fields separated by spaces or tabs, these are: a month name, a day in the month and some text. For example: December 25 Christmas Dec 31 New Year's Eve The order of the month and the day are optional, the program deduces the day by looking whether the string contains an initial numeric character or not. The year defaults to the current year unless the program is given a year number as an argument. This year cannot be abbreviated to two digits because xcal deals with years from year zero. There's a rough validity check on this. The string from the data line is inserted in the appropriate file and will appear in your xcal date strip. Nothing will happen if the string already exists in the file for that day. This means that it's safe to run xcalev at any time, only the strings that have altered in the regular file will be updated. To help with entering the same event for a number of days in one month, you can give a day range with a hyphen Jan 16-21 Usenix SF If you supply the -r option, xcalev will delete all the matching strings that it finds in the appropriate daily file. So, if you want to make radical changes to the regular file, you should run xcalev with the -r option to remove all the current entries from one year, edit the regular file and run xcalev to reload things. OPTIONS
The -r option makes xcalev delete rather than append entries. The -x option makes xcalev operate with Calendar files that are compatible with the xcalendar program. The -f switch is followed by a filename gives an alternative name for the regular file. If the filename does not start with a slash or a dot, then the name of your Calendar directory will be prepended to it. The -d switch is followed by a directory name and specifies an alterative location for your Calendar directory. Your home directory is prepended if the name doesn't start with a slash or a dot. FILES
$HOME/Calendar/* xc<dd><Mon><Year> A data file is day, Month in three letter format and the year. xy<Year> A year directory. xw<Day> A data file for the weekly code, one per day. SEE ALSO
