I am having problems with script scope variables (declared local before any
handler) becoming unset, apparently within individual lines of handlers.
For example, the code
on shwChcStk
ck "chstk: _" & chStk & "_; " & cr & chStk is empty
if chStk is empty then
--debug only; this happens in the debugger.
answer "chStk empty"
breakpoint
initCtr
end if
if the chcStk of me then
lock messages --chStk becomes unset during openstack!
palette chStk
unlock messages
set the width of chStk to the width of chFld
where ck is a logger:
on ck stuff
-- answer stuff
-- breakpoint
put stuff
put stuff & cr after fld "log" of stack "ckwatch"
end ck
First it oddly produces simply "false" as the output, rather than
_chStk_
false
If I comment out from &cr on it produces the first part.
In any event, it can get to "if chStk" is empty with a value for chStk,
open that stack as a pallete, and then have nothing in chStk or chFld two
lines later.
But this isn't entirely predictable, either--if I remove the lock messages
around the palette command, ckStk gets emptied every time, even though
there is nothing in the preOpenStack/OpenStack handlers executes other
than logging of the milliseconds to a global, checks for whether it is
the main stack, and an exit.
The semicolon has a special meaning and signifies the end of a script
statement when used in certain conditions. It looks like the engine is
trying to execute your literal. Try changing the semicolon to a
different character.
And the weirdness continues.
In another section
ck the selectedChunk
produced
word 5 to 4 of field 11
the next line,
put the selectedChunk into pos
put something like
char 10000 to 100007 of field 1
Is the put statement into the message box or another field (of a closed
stack) changing the selectedChunk ???
The ck handler changes the field focus twice, once to the message box
and again to a logging field. The original selection is lost.
