Carriage return mark when using INKEY$

[Fred Katzel]

Hi

I have been using INKEY$ to put text into a form letter set-up.
However, when I press return a musical note appears. When I come
to print out the letter the computer doesn't recognize the carriage
return mark. Is there any way to get the computer to recognize this
mark?

Check out the $LIB IPRINT metastatement in the PB Help File.

IPRINT would be your best bet but another train of thought:

When you press a key, you are apparently printing the character
first then evaluating it for something, possibly to exit a DO/LOOP.

Try evaluating it first. Then, if it's a printable character, go
ahead and print it. Otherwise... (?exit loop?).

Hi

Eric and Mel I'm not familiar with IPRINT and the PB file.
The only thing I have in my manual is the following statement'
".PB: A configuration file for the intergrated environment.
This file allows..." on page 5 of the manual printed in 1989.
Where can I find information on IPRINT?

Mel, I have been using your suggestion all along I was just
wondering if their was some way to test for the return mark when
I come to printing.

Well, first of all, I need to know two things:

1. What version of PB are you using?

2. How are the strings you want printed stored? Are they in
memory or are you basically doing a screen dump?

One suggestion if they are in memory:

temp$ = remove$(temp$,chr$(10))
temp$ = remove$(temp$,chr$(13))

>> or <<

replace chr$(10) with chr$(32) in temp$
ditto with chr$(13)

I have PowerBASIC Compiler Version 3. As I indicate in my last
message I have discovered that the carriage return consist of a
single word with a length of 0 units. I have been unable to use
it to produce a carriage return when I come to printing out the
letter. So I am using <00> as a placeholder, <00< if I want a
carriage return after a placeholder and word< when I want a
carriage return after a word. For a blank line I use a single <.

Thanks

How about posting a code snippet so we can get a better grasp of
what's happening. I don't wanna sound rude but I don't have any
idea of what you are talking about.

Fred,

IPrint is a library included with PB/DOS. I do not know if it
goes back as far as version 3.0. I know it's in my version
3.5.

To use it, near the beginning of your source file, put the
statement:

$LIB IPRINT ON

IPrint is a library that enables Interpreted Print. This is what will
enable true CR/CRLF behavior, instead of the program printing
out chars instead of actual CR's.

Hope this helps!

Cordially,

Clay: $LIB IPRINT has been supported since v2.00 at least.

I dimly recall symbols being printed instead of carriage returns if either a CHR$(13) or a CHR$(10) was present without the other, i.e. a Mac or Unix text file. If my memory is correct on that, then it's likely the same thing would have happened if CHR$(10, 13) were inadvertently used instead of CHR$(13, 10).

An example.....it'e a remake of Input with Inkey so special
keystrokes can be captured. Sorry about the lack of
documentation.

SUB kInput(promptString$,inVar$)
userInput$=""
curln%=CSRLIN
if curln%>(pbvScrnRows-1) then curln%=(pbvScrnRows-1)
plen%=LEN(promptString$)+1
llen%=79-plen%
print promptString$

locate curln%,plen%
do
        myInput$=inkey$
	select case myInput$
        	case chr$(27):userInput$=""
                case chr$(8)
                        if uiLen%=0 then exit select
                        if uiLen%=(llen%-1) then exit select
                	userInput$=left$(userInput$,(uiLen%-1))
                case chr$(9): userInput$=userInput$+space$(5)
                case keycode$(72)	'Up Arrow
                case keycode$(75)	'Left Arrow
                        if uiLen%=0 then exit select
                        if uiLen%=(llen%-1) then exit select
                	userInput$=left$(userInput$,(uiLen%-1))
                case keycode$(77)	'Right Arrow
                case keycode$(80)	'Down Arrow
                case keycode$(63)	'F5
                	if pbvScrnRows=25 then
                        	width 80,50
                        else
                        	width 80,25
                        end if
                        exit loop
                case chr$(13):exit loop
                case keycode$(59): userInput$=userInput$+"F1"
 	       	case else
                	userInput$=userInput$+myInput$
         end select
	 locate curln%,plen%
         uiLen%=LEN(userInput$)
         color 7,0
         print userInput$;
         color 23,0
         print chr$(249);
         color 7,0
         print SPACE$(llen%-uiLen%)
loop
locate curln%,plen%
uiLen%=LEN(userInput$)
print userInput$+SPACE$(llen%-uiLen%+1)
inVar$=userInput$
END SUB

FUNCTION keycode$(codenum%)
	FUNCTION=chr$(0)+chr$(codenum%)
END FUNCTION

Try changing the line:

case chr$(13):exit loop

to

case chr$(13):invar$ = chr$(13) : exit sub

This will by-pass the print statements after the LOOP. I don't
know what invar$ is or does but apparently you need it for
processing elsewhere. If you don't need it elsewhere (it's just
an exit flag), try:

case chr$(13) : exit sub

[Amos Vryhof]

As kInput is written as a Work-alike for Input, the inVar$
would be the "Input Variable"

So:

Input "What?", a$

and

kInput "What?", a$

are equivalent statements.
