MANUAL FOR WINEDIT (BBC BASIC)

This file describes the program WINEDIT which is a function that gives a 
standardised method of text entry to any BBC BASIC program.The useage is
supposed to look like the text entry boxes present in RISC OS.These allow 
cursor editing of the entered text,which is also centred in the box,and 
scrolled from right to left.
The manual and software is (C)1997 SPROW

INSTRUCTIONS-
At the BASIC prompt,type CHAIN"WINEDIT"

The program has tacked onto it an example call - to isolate just the routine 
itself,simply delete the first few lines.

The parameters passed when calling the function allow the setting of:

1)Default string - eg."TextFile"
2)Window width - odd numbers will work best
3)Max length - a beep (VDU7) is emitted if the string is too long
4)Window position - where on the screen the box is to appear.
5)Background colour - your choice.
6)A string of characters to reject - eg."#* " for filenames

The cursor editing status,using *FX4 is preserved during the FN.
You'll need to reset any windows you had,and also the background text colour.
