jBase KEYIN() leaves character in print queue

[Mike Yates]

Is there an option available to prevent this non-Pick result, or is it a bug?

The Rocket documentation mentions nothing and falsely states that backspace is excepted.

As I said before, use the jBASE keyboard independent subroutines. It is more than likely that the bug isn’t where you think.

Sorry guys, but both INPUT K,1 (UNFORMATED gives syntax error) and JBASECommandNext(KeyDescriptionCode,KeyData,Timeout)

leave the character to be printed to screen.

I'll just have to work around it by putting the cursor into an unused area and overwriting.

Other Pick flavours do not do this with KEYIN() though they do for INPUT K,1

I think this example here: https://docs.rocketsoftware.com/bundle/jbase_lib_61/page/btz1666031270568.html

 

Shows this:

 

$INCLUDE JBC.h

$INCLUDE jCmdKeys.h

EQU Timeout TO 100 ;* 10 seconds

CALL JBASECommandInit

* Accept keyboard input until ESC is pressed or the Timeout limit has been reached

LOOP

     ECHO OFF

     CALL JBASECommandNext(RtnNo, KeyData, Timeout)

     ECHO ON

     CRT @(0):@(-4):'KeyDescriptionCode=':RtnNo:' KeyData=':KeyData:

UNTIL RtnNo = cmd_escape OR RtnNo = cmd_timeout DO

REPEAT

CRT

 

 

Where the routine is togging echo to off, then back on for each call.

Oh yes!

My Pr1me days tell me that character echo occurred in the OS terminal
driver, nothing to do with (INFORMATION as it was then) the program. It
happened even before the character got as far as the KEYIN buffer.

You always needed to suppress the auto-echo if you didn't want it.

No, I've tried ECHO OFF, ECHO ON with KEYIN(), INPUT X,1 and CALL JBASECommandNext(RtnNo, KeyData, Timeout)

and the characters (e.g. "[A" for cursor-up) are still displayed!

I've reported this to Rocket under case #00982080 but that was about evaluation installation.
