Problem with tmerge in procedure script

Gabriel wrote on Mar 23, 2009

Hi,

I'm trying to run this simple procedure script:

procedure test ()

real dummy

begin

tmerge (file1,file2 file3 append)

end

and I get:

** Syntax error, line 7
**: tmerge (file1,file2 file3 append)
^ #the upwards arrow, points to the 'a' in append
INTERNAL ERROR: parser gagged
called as: `test ()'

Am I missing something?
Thanks!

You need commas after each argument and a value of some sort for the 'append' param, i.e.

tmerge (file1, file2, file3, append+)

I think Gaba may be intending to do something more like this (his/her example was just a straight copy of the interactive syntax into parentheses and append is actually the value of the positional parameter "option"):

tmerge (file1//","//file2, file3, "append") 

Cheers,

James.

Before I was running the script outside the 'Tables' package, now I've loaded it. Is it necessary to have that package loaded?

I tried this combinations (whit 'Tables' loaded):

1) tmerge (file1, file2, file3, append+)

2) tmerge (file1, file2, file3, "append+")

3) tmerge (file1, file2, file3, "append")

4) tmerge (file1//","//file2, file3, "append")

5) tmerge (file1//","//file2, file3, append+)

and they all get the same error:

parameter 'file1' not found (the file 'file1' is in the working folder)

If the files are actually called "file1" etc. (rather than being stored in variables of those names), you need to do this:

tmerge ("file1,file2", "file3", "append")

I'd suggest reading the guide to IRAF scripting, to understand where this syntax comes from:

Thanks James!

This is how I ended up writing that line:

tmerge ((imname//'.mag.1')//","//(imname//'.mag.2'),(imname//'.mag.3'),"append")

Cheers!
