require 'gui/gtkwd
Debugwd_gtkwd_=:1
require 'gl2'
load 'demos/wd/demos'
NB.wd;~Demos/wd/demos.ijs
NB.Use the above to launch from launchpad
NB. should this be wd 'demos/wd/demos.ijs'
wd'pshow'
I'm trying to update all these little useful things for upgrading my old
relics.
1. Is the D in Debugwd only a capital or could it be small like the others?
2. wiki has no response about launchpad and I only use it when I need to
relax and play minesweeper. How and when is it used?

Subject: Re: [Jprogramming] Control error when loading script into ijx window
(J602)
I would suspect H L C are undefined. My general approach is to
insert smoutput before and after every control switch, eg
smoutput 'a1'
for_i. i.(#a) do.
smoutput 'a2'
currHi=. ". > (i { H)
currLo=. ". > (i { L)
currCl=. ". > (i { C)
if. (0=i) do.
smoutput 'a3'
diffHi=. 0
diffLo=. 0
else. <-------- control error here
smoutput 'a4'
prevHi=. ". > ((i-1) { H)
prevLo=. ". > ((i-1) { L)
diffHi=. currHi - prevHi
if. 0<:diffHi do. pivotHi=. currHi end.
smoutput 'a5'
diffLo=. prevLo - currLo
if. 0<:diffLo do. pivotLo=. currLo end.
smoutput 'a6'
end.
smoutput 'a7'
if. diffLo>diffHi do.
smoutput 'a8'
if. currLo <: ( pivotHi * (1-swing) ) do.
smoutput 'a9'
xx=. xx , currLo
