You have lots of options here.
If the report is a Hold Entry in the spooler, you can send this to a file
using the (I) 'eye' option of the SP-EDIT command. For example, if you want
to send Entry #42 to a file, enter
SP-EDIT 42 (I)
and you will be prompted for the destination "File name and record key".
A more direct way to accomplish this is with the 'jspcmds' command:
jspcmds COPY "filepath filename" job#
For example, the command...
jspcmds COPY "/tmp/printjobs myjob.txt" 42
will 'copy' hold entry #42 to the '/tmp/printjobs' directory with a
filename of 'myjob.txt'.
Should you wish to also delete the spooler entry then use 'COPYDELETE' in
place of 'COPY' in the above command.
***
A form queue can also be created like this:
SP-CREATE FILE PROG cat > /tmp/file.txt
When a printjob is despooled, a file will be created in the specified
directory and will be called 'MyPrintFile'. The caveat of this method is
that each time a job is despooled to this queue, it OVERWRITES the previous
file.
***
The most flexible approach is to redirect spooler output to a user-written
Basic program. What this means is that spooler 'output' (stdout) becomes
the 'input' (stdin) to your program. This gives you total control over the
spooler output. A typical program will capture all of the data to a file
and then do something with that 'file' (like email it, convert it to a PDF
or some other format, ftp it to some other machine, etc, the possibilities
are endless). Output can also be handled line-by-line as it is being
despooled.
Here's some code you can start with:
0001 PROGRAM lptext
0002 INCLUDE JBC.h
0003 id = CHANGE(UNIQUEKEY(),'/',']2F') ;* create a unique item-id for
the print job
0004 tempdirname = '/tmp' ;* This directory must have 'rw' permissions
0005 OPENSEQ tempdirname:DIR_DELIM_CH:id TO outstream ELSE
0006 CREATE outstream ELSE NULL
0007 END
0008 LOOP
0009 numchars = SYSTEM(14)
0010 WHILE numchars DO
0011 INPUT line, numchars
0012 WRITESEQ line ON outstream ELSE NULL
0013 REPEAT
0014 WEOFSEQ outstream ELSE NULL
0015 CLOSESEQ outstream
The next step is to define the form queue. For example, if the program is
cataloged in '/home/bin' then:
SP-CREATE FILE PROG /home/bin/lptext
All that's left to do is assign the queue and print something, e.g.
SP-ASSIGN =FILE
LIST MD SAMPLE 10 LPTR
Note that the above code assumes the system is running jBASE 4 or 5. To get
it to run on jBASE 3 :
1) Replace line 3 with:
id = SYSTEM(21):'_':DATE():'_':TIME():'_':SYSTEM(9):'_':RND(32000)
2) Replace lines 5 through 7 with:
OPENSEQ tempdirname:DIR_DELIM_CH:id TO outstream ELSE NULL
3) Add the line:
openseq_creates = true
to the '$JBCRELEASEDIR/config/Config_EMULATE' file under the appropriate
emulation section, if it does not already exist. This setting allows 'id'
to be created if it does not previously exist.
Hope this helps,
Dan
