I started off by deleting

DelVar A15→B

Text(1,82,"

Text(0,82," LET

and replacing it with simply

1->A

which removes the annoying "LET" in the top right corner and keeps it to numlock, im running into issues with adding the deicmal though. I dont understand how the number string works.

]]>`... XYZθ.",M-5int(.1M)-20,1`

To access the decimal, press [+^{"}]. It won't give you an error, it's just adding the [+] key (95) to the sub( command.

Be sure on **line 8** to change the bold part from `not(A) M<95` to

`:ClrDraw :DelVar A15→B :Text(1,82," :Text(0,82," LET :" →Str1 :Repeat max(M={45,105,21 :‾5→C :Repeat M=23 or max(Ans={21,45,105}) or (not(A)M>40 and not(A)M<95 and M≠44) or max(AAns={92,93,94,102,82,83,84,72,73,74 :C+1-10(C>4→C :Text(29,B,sub(" [",1+(Ans>0),1 :Text(29,B+1," :If M=31 :Then :not(A→A :Text(0,83,sub("LETNUM",3A+1,3 :End :getKey→M :End :If min(M≠{21,105,45,23 :Then :If A :Then :sub("0123456789",27-3int(.1M)+10fPart(.1M)+2(M=102),1 :Text(29,B,Ans :Str1+Ans→Str1 :B+4→B :Else :sub("ABC DEFGHIJKLMNOPQRSTUVWXYZθ",M-5int(.1M)-20,1 :Text(29,B,Ans :Str1+Ans→Str1 :B+4→B :End :Else :If M=23 and 1<length(Str1 :Then :B-4→B :Text(29,Ans," :sub(Str1,1,length(Str1)-1→Str1 :End :End :End`

works very well but doesn't support decimals and requires you to switch to numlock if you want to input numbers. This other routine:

`DelVar A" →Str1 Repeat K=55 Output(1,16,sub("A1",A+1,1 Output(2,16,Str1+"^ //one space afterwards Repeat Ans getKey End Ans-5int(.1Ans→K "* If K-20>16A sub("789**456**123**0.‾**ABC**DEFGHIJKLMNOPQRSTUVWXYZθ'* :?*",K-36A,1 If Ans≠"* Str1+Ans→Str1 A xor K=16→A length(Str1 If Ans≠1 sub(Str1,(K=55)+1,1+(K≠25)(Ans-1-(21=abs(K-34→Str1 If K=25 ClrHome End ClrHome Str1`

supports decimals but is very ugly, brings me to the home screen (which I want to avoid) and also requires numlock. Is there any way to simplify the first routine so that it doesnt require numlock (only number input is possible) but also supports decimals? I don't have coding experience so any help would be much appreciated thank you :)

ps. I tried to provide links to the respective code but im too new to the forum for that. the first routine is off the techniques page and the second is from an old thread I found.
