Borland compiler problem
#- If ESCAPE is hit, copy the content of allocated memory back to str.
#-<span style="color:#FF0000"><b> Make sure before the function ends, deallocates the allocated memory.</b></span>
 
OTHER EXIT KEYS:
* You don't have to individually code every key that exits the editor; all of them apart from ESCAPE use the same code, so just let the cases "drop through" each other.
 
INSERT KEY:
 
#You wanna turn on and off Overwrite every time INSERT key is hit.
#INSERT mode is default value. if you press INSERT once, Overwrite Mode will be turn ON and INSERT mode will be turn OFF.
#If you press INSERT again, INSERT mode will be turn ON and Overwrite Mode will be turn OFF
#I dont think there is anything else you should do with INSERT key beside Toggling INSERT MODE and OVERWRITE MODE.
 
 
Printable KEY:
 
// if( key is withing printable character's code){
// if (*instermode){
// do something with str[*strOffset+ *curPosition]
// Push all the characters on the right hand of the cursor to the right to make room for new character.
// Move the cursor after the new inserted character.
// }
// else{
// do something else with str(.....
// Move the cursor after the new overwrite character
// }
//}
* For INSERT mode, you'll need to increase the length of the string before you push the characters.

I am not the owner of the diagram above. I just want to explain it.
 
*The string will initially start at coordination(column,row).
*Offset is an integer that show how many characters are hidden.
*FieldLength is the length of the display box. It decide the maximum number of character you want to display.
*CursorPos is the cursor position within the display box. For example, if your FieldLength is 10, your cursor position can be from 1-10.
*Max str length is used when FieldLength is 0. It decide the length of your str so that it will fit on the screen(with no wrap).
 
 
=Matrix compiler problem=

Make sure to #include string.h instead of string or you will have many errors if you have used strlen strcpy etc.
 
=Borland compiler problem=
#make sure you follow these instruction to install Borland properly.
#make sure you use the console.cpp,key.h,console.h from /trunk/Console folder.
#In order to compile under borland compiler you need to use the last release 1.3 of the console.
