Using inkey

[ardentcrest]

Any one know how to do something like this

I'm looking to use inkey$ to create a line of text while the program is doing some other things Ie

LOOP
DO THING 1
INKEY(text string)
DO THING 2
IF ENTER PRINT(text String)
GOTO LOOP

any help on this

Yes, use the IN (read port) which does not interrupt.
There is a library already for this.

Code:

#include <keys.bas>
if MultiKeys(KEYENTER) then
   PRINT "Enter pressed"
end if

Multikeys uses KEYxxxx constants (see this source at the end for available constants) and can check for several keys at once, using bOR or | (bitwise OR):

Code:

#include <keys.bas>
if MultiKeys(KEYO | KEYZ) then
   PRINT "Key O, Key Z or both pressed"  ' letter case does not matter!
end if

This could be of help. for other parts of my program

But I dont think its what I'm looking for.

I want to type in a line of text while other things are happening.

Have a look at INPUT.BAS code (a library to simulate INPUT)

Then you might want to store the value of INKEY$. INKEY does not lock your program execution:

Code:

myLine = ""
row = 0

LOOP1:
  DO_THING 1
  K$ = INKEY$
  IF K$ = CHR$(13) THEN ' Enter
    LET row = row + 1
    myLine = ""
  END IF
PRINT AT row, 0; MyLine$;: REM add ; "_"; to have a cursor
GOTO LOOP1

Need help. This compiles with no errors but still will not work. Any help.

Code:

10 dim z$ : let z$="this is a test of an inkey$ editor                 " : gosub 2000 :stop
2000 rem INPUT+
2002 poke 23658,0 : let length=len z$
2004 for row=length to 1 step -1

So much fun on this one. No matter what I do it almost works, but not quite works.

Code:

2022 poke 23658,8 and not peek 23658 : goto 2006

Looking to line 2022. What are you trying to do here?

[ardentcrest]

I believe that just flashes the cursor when a key is pressed.

Silly me had a let row=0 in line 2018, just had to remove it :oops:

Just need now to work out how to get it to print in 42 or 64. And on the bottom two lines.

Still a bit buggy need to work on how ROW works.

[ardentcrest]

Sorry Sorry sorry......

Code:

INK 7 : PAPER 0 : BORDER 0 : CLS

#include <keys.bas>

let length=60 : let rowx=0 : let xx$="<"

NETinputloop:

    if rowx=0 then print at 22,0;xx$ : goto NetJump1 : end if
    print at 22,0; : FOR ii = 0 TO rowx : print chr$(peek (@MyLabel + ii)); : NEXT ii : print xx$;"  "

NetJump1:
    let k=code inkey$ : if k then beep .2,0 : end if
    if k>31 and k<128 then goto NetKeyPress : end if
    if k=13 then end : end if
    if k=12 then goto NetDeleteKey : end if
    goto NetJump1

NetDeleteKey:
    if rowx=0 then goto NETinputloop : end if
    POKE (@MyLabel + rowx), 0
    let rowx=rowx-1
    goto NETinputloop

NetKeyPress:
    if rowx=length then goto NETinputloop : end if
    POKE (@MyLabel + rowx), k
    let rowx=rowx+1
    goto NETinputloop


    MyLabel:
    ASM
    text1:
    ds 1024  ;  1024 bytes of space MAX!!
    END ASM


    MyLabel2:
    ASM
    lenth1:
    ds 1  ;  1024 bytes of space MAX!!
    END ASM

When NetDeleteKey: it should move the cursor back but does not. What am I missing.

[ardentcrest]

OK.............

GOT IT

POKE (@MyLabel + rowx), 0 should be POKE (@MyLabel + (rowx-1)), 0

2 hours looking at that one.....
