In Linux you can run lsof and pipe it though grep for the files you are interested in, for example;
$ lsof | grep db.exe | grep accounts
db.exe    16897      john    6uw     REG      253,0    20012    3413872 /usr/recital100/qa/accounts.dbf
db.exe    16897      john    7u      REG      253,0     4176    3413885 /usr/recital100/qa/accounts.dbx
If you want to check for locks you can use lslk, for example;
$ lslk | grep db.exe | grep accounts
db.exe    16897 253,0 3413872 20012  w 0  0  0 12319   0 /usr/recital100/qa/accounts.dbf
If you don't have lslk installed you can install it with one of the updaters, for example on redhat linux:
$ yum update lslk

When using Recital Web you can maintain the exact state of each cursor between pages like this.

On entry to the .rsp page.

IF type( _session["state"] ) != "U"
    m_state = _session["state"]
    RESTORE DATASESSION FROM m_state
ELSE
    // open up your tables for the first time 
ENDIF

On exit of the .rsp page.
SAVE DATASESSION TO m_state
_SESSION["state"] = m_state

All temporary files created by Recital are stored in the directory specified by the environment variable DB_TMPDIR.

 
In order to have these files stored in memory first create a temporary directory
mkdir /opt/recital/tmp
 
Then mount the directory with the tmpfs command
mount -t tmpfs -o size=1g recitaltmpfs /usr/recital/tmp
 
Then change the DB_TMPDIR variable in the recital.conf to point to the newly created temporary directory.

Recital 10 introduced the ARRAY( ) functions. This function operates in the same way as the PHP ARRAY( ) function. It can be used to declare a dynamic or associative array and optionally initialize it with elements.
// declare an empty dynamic array
a = array()

// declare a simple dynamic array
a = array("barry", "recital", "boston")
foreach a as value
    echo value
endfor

// declare an associative array
a = array("name" => "barry", "company" => "recital", "location" => "boston")
echo "length of a is " + len(a)
foreach a as key => value
    echo "key=" + key + ", value=" + value
endfor

Recital on Linux 64 bit requires certain 32 bit libraries for installation and/or operation.  It also needs to be installed and configured as the root user, or using sudo for those systems without a root login.

For systems that do not have the xterm libraries installed, please install these to use xterm, or set the DB_TERM environment variable to start Recital from a terminal:
DB_TERM=gnome-terminal; export DB_TERM

This setting can be added to the /opt/recital/conf/recital.conf (text) file to make it available system-wide.

Please note that the Recital ODBC Driver for Linux requires a 32 bit ODBC Driver Manager.

Centos 6:

sudo yum install zlib-devel.i686 pam-devel.i686
(and accept dependencies)
Then run the installer in text mode
sudo ./recital-10.0.3-linux32.bin --mode text
Run Recital with sudo the first time, to set the system filetype compatiblity settings.
sudo recital
After saving the compatibility settings, quit to exit, then run Recital as your preferred user.
> quit
$ recital

RedHat / Fedora family:

sudo yum install zlib-devel.i686 pam.i686
(and accept dependencies)
Then run the installer in text mode
sudo ./recital-10.0.3-linux32.bin --mode text
Run Recital with sudo the first time, to set the system filetype compatiblity settings.
sudo recital
After saving the compatibility settings, quit to exit, then run Recital as your preferred user.
> quit
$ recital

 Ubuntu family:

sudo apt-get install ia32-libs 
In later versions of Ubuntu, ia32-libs is obsolete. The following package should be installed:
sudo apt-get install lib32z1
Ubuntu 12.04 and above also require the following:
sudo apt-get install libpam0g:i386
Then run the installer in text mode
sudo ./recital-10.0.3-linux32.bin --mode text
Run Recital with sudo the first time, to set the system filetype compatiblity settings.
sudo recital
After saving the compatibility settings, quit to exit, then run Recital as your preferred user.
> quit
$ recital

I was fascinated to learn that marvel are shipping a complete linux device that runs on a wall plug for less than $100. The device has gigabit ethernet and USB connectivity making it ideal for building home security and surveillance devices that can be connected together. 

This would be an ideal device for Recital Embedded. Details can be found here. Additional information can be found here and this article in Scientific American 8 Big Things to Do with a Mini Server.

Seeing as this device runs linux, nomachine can be installed on it.  

Clearly this device has a lot of uses including acting as a loadbalancer and also as a bunch of loadbalanced application servers that access data on a network using glusterfs or samba. Another great use of this device would to configure it as a rsnapshot server to backup all the machines in your home! Interestingly in quantity the device is only US$50.

Marvell have a development wiki here.
