[ferret_users] get ppl defaults

[Marco van Hulten <Marco.Hulten@xxxxxx>]

Hello,
 
Is there a practical way to use PPLUS parameters in Ferret?
 
ppl list labset
LABEL CHAR HEIGHTS
HLAB1= 1.60E-01 HXLAB= 1.20E-01 HYLAB= 1.20E-01 HLABS= 1.20E-01
 
I want to use those variables:
 
let factor = 1.5
ppl labset, HLAB1*factor, HXLAB*factor, HYLAB*factor, HLABS*factor
 
However, I don't know how I can access HLAB1.  It's not ($PPL$HLAB1):
that doesn't exist.
 
Even better would be a way to retrieve the default values (as I want to
override those).  If I can use the present values, this would be fine
as well, because then I just need to issue a PPL/RESET to get the
default values.
 
 
Is there also a PPL LIST command to get the AXLSZE settings or defaults
that define the heights of the numbers next to the axes?
