Re: Fprint error

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi all,
After communicating off-line, Toni and I determined that this was due to
a sequence like this in his script:

 yes? set mode meta
 yes? plot  var1

 yes? ppl axlsze 0.14,0.14
 yes? ppl labset 0.12,0.15,0.15
 yes? ppl plot

 yes? plot/over var2

The PPL commands need to follow a PLOT/SET command.  As they
stand above, the PLOT command is a complete plotting command,
and then the PPL PLOT causes Ferret to close the metafile and open
a new one.  The command

  yes? plot var1 
should be

  yes? plot/set var1

Alternatively, since the AXLSZE and LABSET commands are not reset
by Ferret commands, they could also be issued at the start of the journal
file and would apply to all subsequent commands.  So the script could also
be written as follows

 yes? set mode meta
 yes? ppl axlsze 0.14,0.14
 yes? ppl labset 0.12,0.15,0.15

 yes? plot  var1
 yes? plot/over var2

Look up "PPLUS, for plot customization"  in the Ferret Users Guide for a
discussion of the different plot settings made by Ferret and PPLUS commands.
