[daip] A simple request for PRTAB

[Craig Walker]

PRTAB has two inputs for controlling how many entries for a column are 
shown - NCOUNT and BDROP/EDROP.  To restrict what is shown, one must 
specify something for both.  If either defaults, everything is shown, 
not matter how the other is set.  This means that you can never show, 
say, the entries for IF's 5-7 without getting IF 1 too because NCOUNT 
must be set and it starts at 1.  If you just simply want to restrict the 
size of the print with NCOUNT, you must also specify non-default values 
for BDROP and/or EDROP or you still get everything.

I suggest that, if one parameter is specified, that the other not take 
the default.  If both are specified, then go ahead and conform to both 
requests as it does now (I can see reasons for that).

While at it, there is an unfortunate interaction with DOFLAG between 
CALIB and PRTAB.  A value good for one is not good for the other and I 
keep tripping over it.  PRTAB aborts with DOFLAG set to reasonable CALIB 
values (>1).

Cheers,

Craig
