Since I use the debugging every now and then, I thought it would be easy to
answer Ruda's question but it was not. My first thought is that the name
of the verb in question is not "gettplog" but "gettplot_jzplot_". However
there appears to be both "gettplog_jzplot_" and "gettplog_jwplot"
which appear to be identical. However, setting stops in both failed to
work:
dbstop 'gettplog_jwplot_'
dbstop 'gettplog_jzplot_'
'ylog 1' plot 1 2 0 3
|NaN error: gettplog
| pos=.min+step*i.>:>.(max-min) %step
|gettplog[:11]
However, at this point I was able to do this:
13!:19'' NB. Cut back the stack
13!:1'' NB. Look at stack
* x gettplog y
|getticpos[:3]
| 'Step Min Max Int TicPos'=.pm getticpos Int;TIC;Min;Max;LOG;mtc
|getaxis1[67]
...
dbstop 'gettplog' NB. Set stops
13!:4'' NB. Resume execution
|stop: gettplog
| 'int tic lmin lmax log cnt'=.y
|gettplog[:0]
So, I am properly stopped at this point but I can't figure why my initial
stops don't have an effect. At least the above will provide a work-around.
