Error running [RC] Plot coordinate pairs

[Brandon Parker]

There are issues with the Locate command not locating in the MainWin, but I'm not certain if the Locate command has actually even been implemented completely yet.

Also, when the program gets to the first iteration of the For...Next loop below the IDE issues a warning at the bottom that states:

"6.07 could not be reduced to the desired generality"

For i = 0 To 9
   Locate (x(i) * 4) + 2, (21 - (y(i)/ 10))
   Print "."
Next i

Here is the full program code that works normally in LB 4.5.1
'Plotting coordinate pairs MainWin - Style
For i = 0 To 9
   x(i) = i
Next i

y(0) = 2.7
y(1) = 2.8
y(2) = 31.4
y(3) = 38.1
y(4) = 58.0
y(5) = 76.2
y(6) = 100.5
y(7) = 130.0
y(8) = 149.3
y(9) = 180.0

Locate 4, 22
For i = 0 To 9
   Locate ((i * 4) + 2), 22
   Print i
Next i

For i = 0 To 20 Step 2
   Locate 0, (21 - i)
   Print (i * 10)
Next i


For i = 0 To 9
   Locate (x(i) * 4) + 2, (21 - (y(i)/ 10))
   Print "."
Next i

For i = 0 To 9
   Print #gwin, "Place " + str$((i * 40) + 25) + " 440"
   Print #gwin, "|" + str$(i)
Next i

For i = 0 To 20 Step 2
   Print #gwin, "Place 1 " + str$(417 - (i * 20))
   Print #gwin, "|" +Right$("      " + str$(i * 10), 3) + "-"

"6.07 could not be reduced to the desired generality"

could be fixed by INT'ing these 6.07
and LOCATE seems only work if area in mainwin is pre-printed, say with spaces

So workable mainwin LB5 code:
'Plotting coordinate pairs MainWin - Style
For i = 0 To 9
   x(i) = i
Next i

y(0) = 2.7
y(1) = 2.8
y(2) = 31.4
y(3) = 38.1
y(4) = 58.0
y(5) = 76.2
y(6) = 100.5
y(7) = 130.0
y(8) = 149.3
y(9) = 180.0

'prepare space for LOCATE
for i = 1 to 30
   print space$(60)
next

Locate 4, 22
For i = 0 To 9
   Locate ((i * 4) + 2), 22
   Print i
Next i
print

For i = 0 To 20 Step 2
   Locate 0, (21 - i)
   Print (i * 10);
Next i

For i = 0 To 9
   Locate (x(i) * 4) + 2, int(21 - (y(i)/ 10))
   Print "."
Next i
end

Even though that serves as a work-around, both things are still unexpected issues trying to run simple code from LB4.x.x

These are just bugs that will be fixed like any other. 

[Brandon Parker]

Sounds great Carl!

That's what testing is all about. Finding workarounds for things is great and I am definitely in the subset of people that find workarounds to push the limits of LB often. I just didn't want anyone new to the forum to think that just because a workaround has been found the bug could be ignored...

I just hope workarounds could help to better understand what's going on.

The bug report was enough in this case.  I've fixed the "6.07 could not be reduced to the desired generality" error already.  That happened because I was trying to convert a DOUBLE to a SHORT using the wrong function.

I'm actually going to replace the text editor widget used in the mainwindow with a better one, so I haven't fixed the other half of the bug yet.  The new widget should fix font related problems I'm having in the mainwindow and should also be faster.

Just a note that the code sample you posted now works properly in LB5 build 353.

Great news Carl!

It is awesome to see large amounts of progress on LB5!!

And the new main window is faster. 

[Brandon Parker]

Yes!!! Everyone loves more speed ...
