  2.           Command                                    1986/No. 17

  4.           ______________________________________________________
  5.  
  6.           Purpose:  Pops up a calendar window for any month from
  7.                     January, 1583 to December, 9999.
  8.  
  9.           Format:   POP-CAL          (loads command into memory)
  10.                     Alt-C                Toggles calendar on/off
  11.                     Right-Arrow                Advance one month
  12.                     Left-Arrow                    Back one month
  13.                     Up-Arrow                    Advance one year
  14.                     Down-Arrow                     Back one year
  15.  
  16.           Remarks:  POP-CAL is a memory-resident utility and
  17.                     should be loaded into memory before you call
  18.                     up any applications programs.  Normally, you
  19.                     would simply enter POP-CAL as one line in
  20.                     your AUTOEXEC.BAT file.
  21.  
  22.                     POP-CAL takes the current month and year as
  23.                     its initial value.  It subsequently remembers
  24.                     your last-used calendar, facilitating
  25.                     repeated references.
  26.  
  27.                     Notes:
  28.  
  29.                     1.   You can use DEBUG to change the default
  30.                          Alt-C toggle key by replacing the
  31.                          Alt-key scan code value at offset :014B.
  32.                          The default value is 2E, which will
  33.                          appear, followed by a period, in
  34.                          response to the E command shown below.
  35.                          Enter only the new scan code, not the
  36.                          2E.  Thus, to change the program to use
  37.                          Alt-Q (scan code 10) you would enter:
  38.                             DEBUG POP-CAL.COM
  39.                             E 14b 10
  40.                             W
  41.                             Q
  42.  
  43.                          The hex values for the various scan
  44.                          codes are given in Appendix E of the IBM
  45.                          BASIC manual (3.0) and also in the "Scan
  46.                          Code Value Table" in connection with
  47.                          SLASHBAR.COM.
  48.  
  49.                     2.   While POP-CAL has been tested for
  50.                          compatibility with a number of other
  51.                          memory-resident programs, there is
  52.                          always the possibility of a conflict
  53.                          with other TSR (Terminate-Stay-Resident)
  54.                          programs.
