[gradsusr] is "read" deprecated?

[Jennifer M Adams]

The ‘read’ function is alive and well. Perhaps you are trying to use it as a grads command instead of a script command? Or maybe you are forgetting to capture the information returned by read into another script variable? You should share (in the simplest way possible) your specific use of ‘read’ and the error message you get back.

file=‘blah.txt’
rest=read(file)
line1=sublin(rest,1)
line2=sublin(rest,2)
retc=subwrd(line1,1)
if (retc=0)
* do something with the string in the script variable called line2
else
  say ‘finished reading ‘file
endif

http://cola.gmu.edu/grads/gadoc/script.html#intrinsic

but as of grads-2.0.2 and above, this intrinsic function
appears to be unrecognized.  Having the option to read
some simple ASCII data and add a few extra marks on
a graphic seems worthwhile.  Is it now only an option
to do so via, say, pygrads?
