[PD] abstractions $ variable inconsistency

[Matt Barber]

Hello,

Please note the most important place you need a $ inside a string is
for dynamic patching within an abstraction, where you sometimes need
to send messages to pd-$0_string .

A work around for 0.39 and lower is something like the following:


[loadbang]
|
[f $0]
|
[makefilename pd-%d_string]


which can be saved in [symbol] or [pack] and used in messages later.
You can use this for other $ variables and strings, of course, but it
seems cleaner and better style to use $ at the beginning of strings
when possible, at least for the time being while many of us are still
using < 0.40.

Thanks,

Matt
