Here's some routines that I wrote to use in the Windows Console only.
Some were used in other Basics to speed up the print process for
screens and boxes. I see where I can
use them in FB also, so I made
copies in case others might be interested in them.
These first 3 routines does Block copy as do the last two. They will do the whole thing in one swoop, color
screen and all, without using any FORNEXT loops to process the characters and its colors one character at a time into
memory.
' For FreeBasic,
' You can use these launchers to Launch screens made with Conascii.
' Most launchers are generated with the screens made by Conascii, but here's a few more.

lpReadRegion.Bottom = row - 1

If Source
= 1 Then
sBuffer(Dest) = Space((row+1) * (col+1) * 4)

Strptr(sBuffer(Dest))),_

GetKeys
Getkeys is a Routine that gives a Keynumber for each key you hit on
the
Keyboard. The ones that already uses Ascii numbers keeps those numbers,
but the rest are assigned a
special number, which you will have to hit
the key to see what it is in the test program. It also gives Mouse
Buttons
and locations.
I got the CVI example from off one of the forums, but I forgot where.
I use examples
similiar to it in other Basics. CVI(k$ + CHR$(0)) works
with QB, PBdos and PBCC .
Sub GetKeys (Keynumber As Integer, k As String, Rgt As Integer, _
Lft As Integer, cRow As Integer, cCol As Integer)
Dim buttons As Integer
Keynumber=0 : Rgt=0 : Lft=0 : cRow=0 : cCol=0
Locate 1, 1, 0
Do
GetMouse cCol, cRow,, buttons
If buttons And 1 Then lft = 1 : Exit Sub
If buttons And 2 Then Rgt = 1 : Exit
Sub
k = Inkey$
Sleep 1
Loop While k = ""
If Asc(k) > 31 And Asc(k) < 127 Then
keynumber = Asc(k)
ElseIf Asc(k) = 27 Then
keynumber =
27
ElseIf Asc(k) = 8 then
keynumber = 8
ElseIf Asc(k) = 9 Then
keynumber = 9
ElseIf Asc(k) = 13
Then
keynumber = 13
Else
keynumber = Cvi(k +k+ k+k) : Sleep 10
End If
End Sub
Dim As Integer kn, rt, lt, rw, cl
Dim ch As String
Do
GetKeys kn, ch, rt, lt, rw, cl
If rt Then Print " Right button", rw, cl
If lt Then Print " Left button" , rw, cl
If kn Then Print Kn , ch
Loop
Until kn = 27
End
Note: This was written for earlier versions of
Freebasic, Freebasic may now have better key getting routines.

to process single characters or its attributes into memory.
