Thanks to j...@souslelogo.com for the suggestion that hasMemory(bytes)
might be useful. I haven't tried this yet.
Thanks to <ad...@flexiblelearning.com> for replies to my other
questions.
On the memory cost of writing fld "data" to tVar
Q2. Of course it does, but the same condition is in place in all three
tests. And the data has to come from somewhere.
My question was whether we could save memory (and if there is some
other downside) if we write
repeat for each line L in fld "data"
rather than
put fld "data" into tVar
repeat for each line L in tVar
On the rules about "repeat for":
Q2. This 'repeat for each' rule refers to not modifying whatever
'each'
refers to. In this case, 'each' is a line and the number of lines in
unchanged so I am not changing the internal line pointers set up by
the
engine at the start.
If your approach works consistently, it implies that LiveCode's
dictionary is too restrictive when it says (regarding "repeat for
each labelVariable in container"):
"Important! In any of the for each loops, you should not change the
labelVariable or container in a statement inside the loop. Doing so
will not cause a script error, but will almost certainly produce
unexpected results."
