[gradsusr] Moving from one grads version to another

[Martin Cuma]

Hello,

We are trying to move from older grads (2.0.a1) to newer, and have some issues. 
When plotting variables from the same .ctl files with grads 2.0.2.oga.2 that 
plot successfully with grads 2.0.a1.  For example, we can successfully plot a 
variable, ugrdprs with grads 2.0.a1, but get the following error with grads 
2.0.2.oga.2:

ga-> d ugrdprs
Syntax Error:  Invalid Operand
     'ugrdprs' not a variable or function name
     Error ocurred at column 1
DISPLAY error:  Invalid expression
     Expression = ugrdprs

The variables affected have long strings in the .ctl file, for example:

UGRDprs   31,100  0,2,2 ** (1000 975 950 925 900 850 800 750 700 650 600 550 
500 450 400 350 300 250 200 150 100 70 50 30 20 10 7 5 3 2 1) none U-Component 
of Wind [m/s]

When we query the file in grads 2.0.a1, the first part of the string is 
provided:

ugrdprs 31 0 ** (1000 975 950 925 900 850 800 750 700 650 600 550 500 450 400 
350 300 250 200 150 100 70 50 30 20 10 7 5 3 2 1) none U-Compo

However, when we query the file in grads 2.0.2.oga.2, the latter part of the 
string is provided:

ent of Wind  31  0,2,3  ** (1000 975 950 925 900 850 800 750 700 650 600 550 
500 450 400 350 300 250 200 150 100 70 50 30 20 10 7 5 3 2 1) none V-Component 
of Wind

It looks like the long string truncation happens from the left in 2.0.a1 and 
from the right in 2.0.2.oga.2.

Any thoughts on why can this be?

Thanks,
Martin
