- DVCAL is a simple calendar display written for Desqview 2.0+.
- The program has the capability to display a range starting with
- January, 1592 to December, 9999. Three key groups are provided
- for moving by month, year, and century. This is the third
- addition to a series of 'desq-top' utilities for Desqview and
- follows the same basic ideas as the previous programs by being
- simple to use, quick to respond, and requiring a minimum of system
- overhead.
-
- You are granted permission to distribute this program with the
- stipulation that NO remittance is accepted for either the program
- or handling and distribution charges. This program may not be
- distributed with other programs on disk if a charge is incurred
- for any program or for the medium. In other words, if there is
- a charge involved then you do not have permission to include this
- program, period!

- I am slowly but surely learning assembler and this is my most
- ambitious to date. I believe I have put together a compact
- calendar that is both simple to use as well as being fairly
- quick. The program is capable of displaying a monthly calendar
- for the years 1592 through 9999. Three modes are provided for
- moving through the calendar, month, year, and century.
-
- Desqview routines used:
-
- 1: Checks for the presence of Desqview and exits with an error
- if Desqview is not found.
-
- 2: The program writes directly to the screen buffer provided by
- Desqview.
-
- 3: The program releases the rest of the time slice when ever it
- finishes a screen and also after determining that no
- key has been pressed.
-
- Requirements:
-
- Desqview 2.0 :You MUST have this version or later
-
- Dvcal.com :the executable program
-
- Dc-pif.dvp :the program information file used by desqview
- (see next section)
-
- Reasonable compatability with the 'standard' IBM is assumed when
- running this program. I use interupt 16h to check for key
- strokes pending and to retrieve the same.
-
- Program information file:
-
- I have provided the 2 screens from change a program to illustrate the
- required settings should the Dc-pif.dvp be missing or incorrect.
- Five points should be noted:
-
- 1: Memory size is set to 4k. More is not needed, less will
- produce an error message.
-
- 2: Maximum and starting screen size is set to 16 for the height
- and 34 for the width. Increasing values will distort the
- display. Decreasing these values can cause serious problems
- when the program tries to write to memory that is not
- allocated to it.
-
- 3: All memory options on the Advanced screen are set to zero.
- changing this will only allocate memory to the program
- that will not be used and is therefore wasted.
-
- 4: The close on exit to DOS option is set to yes. This
- allows Desqview to use its own shell.com instead of
- command.com to load the program. This saves a nice
- chunk of memory that would otherwise be wasted. In
- addition, the escape key will close the window as well
- as exiting the program.
-
- 5: The program will appear on the Add a program (other)
- menu as Desqview Calendar. Keep this in mind in case
- you have a problem finding it.

- Display Control:
-
- Three keys are used to control the program function.
-
- 1: Page Up: Displays the previous month
-
- 2: Page Down: Displays the next month
-
- 3: Ctrl-Page Up: Displays the previous year
-
- 4: Ctrl-Page Down: Displays the next year
-
- 5: Ctrl-Home: Display the previous century
-
- 6: Ctrl-End: Display the next century
-
- 7: Home: display calendar for current system date
-
- 8: F1: Toggles a quick reference display of the above
- 7 keys.
-
- 9: Escape: Exits the program. Close the window when
- the 'Close on exit to DOS' option is set to Y.
-
-
- Compatability:
-
- This program has been successfully run on the following
- three machines:
-
- 1: Compaq 386 (color)
-
- 2: IBM 8mhz AT (monochrome graphics)
-
- 3: My 8mhz XT. (color) This machine is an example
- of the extreme in that the parts were purchased
- from at least 7 different manufactures, none of
- which are known for their large market share.
- The CPU is a NEC V20 and the BIOS is by PHEONIX
- (version 2.26)
-
- The End:
-
- I have written this program because I have not found a
- satisfactory alternative. I have learned a little more
- about assembler along the way and consider that sufficient
- compensation for the time and effort spent on this
- program. I do have an EGO so feel free to send comments
- using one of the methods provided above. Users that are
- in the same stages of learning assembler as myself may
- have a copy of the source as an example of actual uses
- for the routines Quarterdeck provides. Experienced
- assembler programmer's will be bored and only point out
- all the different areas where my ignorance of assembler.
