POP-CAL Leo Forrest
Command 1986/No. 17


Purpose: Pops up a calendar window for any month from
January, 1583 to December, 9999.

Format: POP-CAL (loads command into memory)
Alt-C Toggles calendar on/off
Right-Arrow Advance one month
Left-Arrow Back one month
Up-Arrow Advance one year
Down-Arrow Back one year

Remarks: POP-CAL is a memory-resident utility and
should be loaded into memory before you call
up any applications programs. Normally, you
would simply enter POP-CAL as one line in
your AUTOEXEC.BAT file.

POP-CAL takes the current month and year as
its initial value. It subsequently remembers
your last-used calendar, facilitating
repeated references.


1. You can use DEBUG to change the default
Alt-C toggle key by replacing the
Alt-key scan code value at offset :014B.
The default value is 2E, which will
appear, followed by a period, in
response to the E command shown below.
Enter only the new scan code, not the
2E. Thus, to change the program to use
Alt-Q (scan code 10) you would enter:
E 14b 10

The hex values for the various scan
codes are given in Appendix E of the IBM
BASIC manual (3.0) and also in the "Scan
Code Value Table" in connection with

2. While POP-CAL has been tested for
compatibility with a number of other
memory-resident programs, there is
always the possibility of a conflict
with other TSR (Terminate-Stay-Resident)

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
