Eric:

Your routines would work fine in Xy3+, with minor changes. A few bits
are Xy4-only, to wit:

- Func ES to cancel a DF block; use func YD or XD instead.
- BC  to put text on the CMline; you need BC 

Why do you use a "permanent" Save/Get? The contents stay in memory
after the program ends, an inefficient use of resources. Unless you
need to retrieve the contents for some reason, use a S/G in the 01-99
range instead.

Also, it's advisable to preface your DeFine operations with a
func YD; otherwise the program bombs if something is already DeFined.

Thus the Xy3-ready versions would look like the following (Jumbo U2
users -- Xy4 only! -- can hit DECODE to translate the pseudo-
code into usable XPL):

(1):
XPLeNCODE v2.0
b-gin [UNTITLED]
[YD_][DF_][CR_][DF_]{<}SV01{>}[YD_][BC_]sea |{<}PV01{>}|
-nd
XPLeNCODE

(2):
XPLeNCODE v2.0
b-gin [UNTITLED]
[YD_][DF_][CR_][DF_]{<}SV01{>}[YD_][SI_][BC_]cva |{<}PV01{>}|
|[CL_][GT_][CL_][CL_][GH_]
-nd
XPLeNCODE

Cheers.

-> Whenever I want to do a search for an unrecognizable character
-> in a file that someone has sent me, I put the cursor on the
-> character and run the following program (from the kbd file):
->
-> {..} = function all, ≪...≫ = guillemets
->
-> (1)    {DF}{CR}{DF}≪SV999≫{ES}{BC}sea |≪GT999≫|
->
-> If I know that the unrecognized character is may e-mail
-> program's substitution for a known character (e.g. when I get
-> Greek theta and know that it's supposed to be e+acute), I run
->
-> (2)    {DF}{CR}{DF}≪SV999≫{ES}{SI}{BC}cva
-> |≪GT999≫||{CL}{GT}{CL}{CL}{GH}
-> ...
-> Does this work only in Xy4? or can it be adapted for use in
-> Xy3+?
