83Plus:Basic:New Tokens on the 84 Plus

The title of this article is incorrect because of technical limitations. The correct title is 83Plus:Basic:New Tokens on the 84+.

The TI-84(SE) has several new tokens. These tokens will not work on the 83's.

Tokens

checkTmr(

• Hex: $EF02
• Syntax: checkTmr(offset
  • offset is a decimal number to add to the value returned.
• Returns: Decimal value of clock ports

ClockOff

• Hex: $EF0F
• Syntax: ClockOff

ClockOn

• Hex: $EF10

dayOfWk(

• Hex: $EF06
• Syntax: dayOfWk(year,month,day
• Returns: Number, where 1=Monday, 2=Tuesday et cetera

ExecLib

• Hex: $EF12
• Notes: This is used with OpenLib(

getDate

• Hex: $EF09
• Syntax: getDate→⌊ALIST
• Returns: {year,month,day} (regardless of getDtFmt)

getDtFmt

• Hex: $EF0C
• Syntax: getDtFmt→[a variable]
• Returns: A number which tells you what date format the user has requested to use on the MODE screen. Either 1, 2, or 3.

getDtStr(

• Hex: $EF07
• Syntax: getDtStr(date format
  • I would presume date format is the same as the numbers used for getDtFmt

getTime

• Hex: $EF0A
• Sintax: getTime→⌊ALIST
• Returns: A list, in the format: {hour,minuet,second

getTmFmt

• Hex: $EF0D
• Returns: Either 12 or 24, depending on weather the user likes 12 or 24-hour mode clocks.
• Notes: Works alot like getDtFmt

getTmStr(

• Hex: $EF08
• Syntax: getTmStr([12|24]
  • It takes either 12 or 24, but I would guess that there are other values you could include after that to get the seconds.

isClockOn

• Hex: $EF0E
• Notes: The way this one works, to test if the clock is on, just do If isClockOn or If not(isClockOn).

OpenLib(

• Hex: $EF11
• Notes: This is used to interface with an application. However, no apps have been released to make of this (yet) *pokes Michael Vincent with a flash drive*

setDate(

• Hex: $EF00
• Syntax: setDate(year,month,day
• Notes: DtFmt does not affect this.

setDtFmt(

• Hex: $EF03
• Syntax: setDtFmt([1|2|3]
  • 1, 2, and 3 should be M/D/Y, D/M/Y, and Y/M/D, respectivly.
• Notes: This is used to set the date format shown on the MODE screen

setTime(

• Hex: $EF01
• Syntax: setTime(hour,minuet,second
• Notes: This does not care about TmFmt

setTmFmt(

• Hex: $EF04
• Syntax: setTmFmt([12|24]
  • Takes either 12 or 24. 12 for AM/PM, 24 for 24-hour mode clock
• Notes: Changes the time time format shown on the MODE screen

startTmr

• Hex: $EF0B
• Notes: This works just like checkTmr(0), execpt smaller.

timeCnv(

• Hex: $EF05
• Syntax: timeCnv([a number of seconds]
• Returns: A list that converts the number of seconds into {days,hours,minuets,seconds
• Notes: You may wish to use this with checkTmr( to bump the time up or down a few seconds

Notes

Time is not a new token for the 84.

ti83plus.inc does not define any tokens as starting with $EF, and all these new tokens start with $EF. $EF is the second byte of some two-byte tokens.
