3.1EA1: Column Headings don't display when using SQL*Plus formatting

Question

The Col[umn] command doesn't show the column headings or the total lines in sqldev. This SQL command:
-- Size per datafile
col tablespace_name format a10 head 'Tablespace'
col file_name format a40 head DataFileName
col cursize form 999.99 head "CurrSize|GB"
col maxsize form 999.99 head "MaxSize|GB"
col Autoextensible form a4 head "Auto"
break on tablespace_name
compute sum label Total of cursize maxsize on tablespace_name
select tablespace_name,
file_name,
bytes/1024/1024/1024 cursize,
maxbytes/1024/1024/1024 maxsize,
autoextensible
from dba_data_files
where tablespace_name = 'TS_DP'
Looks like this in sqldev:
TS_DP /ddawno/oradata/data01/dp_data22.dbf 1.76 1.76 YES
TS_DP /ddawno/oradata/data01/dp_data01.dbf 1.76 1.76 YES
22 rows selected
But looks like this in SQLPlus:
CurrSize MaxSize
Tablespace DataFileName GB GB Auto
TS_DP /ddawno/oradata/data01/dp_data22.dbf 1.76 1.76 YES
/ddawno/oradata/data01/dp_data01.dbf 1.76 1.76 YES
Total 36.20 31.64
22 rows selected.

Hi, thanks for the response.
No, I do not have "set heading off" somewhere. What I pasted into my original post is the entire script that I am running from the worksheet, and I am not using a startup script.
Odd that the column formatting works for you, yet the list of unsupported commands that you pointed me to says that col[umn] is not supported. Help column from within sqldev contradicts that documentation, showing that col[umn] is supported, but only for the "NEW_V[ALUE] syntax."
Wow, there's nothing like enabling the most obscure keyword just to be able to say that a function is supported. Oh, well, at least the scripts that I download from the web run now. In 3.0 they died with a hard error just because the col[umn] keyword was used.
