Global String Reference

Global String (STBL)	Usage
$arraysep	Delimits field names from array element numbers. If $arraysep is "__", then a cgi name of amount__5 would be interpreted as cgi.amount[5]. The default separator is a hyphen (-), but because this conflicts with Javascript code, it may be necessary to use another value valid in Javascript variable names but one that does not conflict with names used in the application. If the value is changed, it must be set before utcgi.wbb is CALLed.
$bbweb-version	Stores the version of the BASIC Web Utility.
$bodyopt	Use in standard structure options added to the <body> tag.
$cgi	Stores the data of cgi$ for use in programs that do not have access to cgi$.
$cgitpl	Stores the string template definition for $cgi.
$commdir	Points to the shared directory used by utwatch.wbb and bwu2.sh , if the shared directory model is used by the application. Used by utwatch.wbb and should match the value used by bwu2.sh .
$cookies	Triggers the placement of cookies on the browser. This must be set to a comma-delimited list of names that reference global string values to be stored as cookies. This must be set before the first CALL to utsend.wbb.
$cr	The carriage-return portion of a text file line termination. Null on UNIX and ASCII, 13 on Windows.
$env	Stores the data of env$ to use in programs without access to env$.
$envtpl	Stores the string template definition for $env.
$errdesc-errnum	The uterr.wbb program reports the description "An error occurred" for any error value passed to it. It does, however, look for this global string for the description. For example, setting $errdesc-0 to "A locked file or record was encountered" would report that message for an error 0.
$filename-fieldname	Stores the user-entered file name when a file upload field is posted from a HTML form. When stored on the Web server filesystem, the BASIC Web Utility retains the file extension but renames the file uploaded to a run-time defined name. The original name is stored in this global string.
$imagelib	Provides a path to the physical location of image files. Any data field with a user attribute of image=y is interpreted by the BASIC Web Utility to be an image file. In creating the HTML <img src=> tag, the BASIC Web Utility attempts to open the file. If the file cannot be located by a PREFIX search, define $imagelib as the physical path to open the file. The BASIC Web Utility can then determine the width and height of both .gif and .jpg images and create a <img> tag that is rendered faster by most browsers.
$imageurl	This is added to the beginning of any <img src=> tags generated by the BASIC Web Utility. If $imageurl is "/home/images/", and a data field with a user attribute of image=y is "1001.gif", the BASIC Web Utility defines the tag as <img src="/home/images/1001.gif">. Note the $imagelib can also help in determining the width and height for the tag.
$infile	An internally maintained value used by utwatch.wbb and utcgi.wbb.
$list	Stores the result of uthtmfil.wbb, uthtmkey.wbb, and uthtmsel.wbb. Use this to merge the results into HTML documents as "[$list]".
$mailerror	Can be defined on a UNIX system with the mail command to notify an administrator of an error reported by uterr.wbb. It should be set to an email address reachable by the Web server. It should not be set on a non-UNIX system.
$memospacer	If the utmmoout.wbb program tries to retain leading spaces, set this global string to "y" to have the BASIC Web Utility add <spacer size=cols> to the text. Browsers that support the <spacer> tag will then render the indents.
$memotable	As with the $memospacer, this attempts to retain leading spaces on lines, but uses a <table> structure, with <td colspan=cols> tag to control the spacing. Set this global string to "y" to trigger this behavior.
$moreurl	Stores a URL suitable for continuation of a list generated by uthtmfil.wbb, uthtmkey.wbb, or uthtmsel.wbb. All values sent in CGI$ are retained. Suitable for use in HTML text as <a href="[$moreurl]">More records&ldots;</a>.
$otherhead	Used in standard structure options, added before the <body> tag. Use this tag to add <meta> tags or other tags that go between the <head> and </head> tags (except <title>.)
$outchan	An internally maintained value used by utsend.wbb.
$outfile	An internally maintained value used by utwatch.wbb.
$sesage	If session tracking is turned on (with the $sestpl global string), this value determines the age in hours a session cookie lasts. The default is 24. Setting it to 0 results in the session expiring when the browser is closed.
$sesid	An internally maintained value if session tracking is turned on.
$sesrec	Stores the current session record, whose structure is defined with $sestpl.
$sessioncookie	An internally used value for cookie management.
$sestpl	Stores the string template definition for session state management. If defined before utcgi.wbb is CALLed, the BASIC Web Utility manages a session record using this as the record definition.
$stdfoot	Used in standard structure options. Points to a file to be appended to the end of all output. Used by utexit.wbb.
$stdhead	Used in standard structure options. Points to a file to be placed just after the <body> tag is printed by the first call to utsend.wbb.
$tempdir	Points to a directory to be used for temporary files. If it is not defined, the BASIC Web Utility looks for the environment variable TEMP. Then, use the /tmp directory on UNIX, or the current (cgi) directory on Windows. Used by uttempfl.wbb.
$title	Triggers the standard structure options and is placed in the document header inside <title>&ldots;</title> tags.
$url	An internally maintained value used in Win-CGI.
$urltpl	An internally maintained value used in Win-CGI.
$usechan	Used to force the BASIC Web Utility to search for available channels above this value. If the BASIC Web Utility conflicts with other programs used in an application, set this value to a high number to prevent the BASIC Web Utility from using the UNT value to open files.
$waitsec	Used by utwatch.wbb to pause a specified number of seconds between directory scans. The default is one second.
