$Web Sels Check

<section begin="desc" />Check string against a delimited list of strings<section end="desc" />

$Web_Sels_Check validates that a string matches one of a delimited list of strings. Note that although this is provided for a sort of symmetry in the $WEB_SELx functions, it is somewhat unnecessary; a simple $ONEOF could do basically the same thing. An overview of the $WEB_SEL_x functions is provided in $Web_Selp.

$Web_Sels_Check takes three arguments and returns a numeric result code; for some types of errors, the current User Language request is cancelled.

Syntax

<section begin="syntax" /> %RC = $Web_Sels_Check(delimited_strings, selected_value, - option_keywords) <section end="syntax" />

delimited_strings	A string containing a delimited list of strings which are used to check the string. The first character of this argument is the delimiter that separates the values. The string should not contain a trailing delimiter unless one of the values is the null string, which is unlikely, at least when used with select option lists. This is a required argument.
selected_value	A string which is checked to see if it is equal to one of the delimited strings. This a required argument.
option_keywords

A string of blank-separated keywords specifying special processing for this $function; it can contain any of the following:
CANCHECK	Cancel request if selected_value not equal to any of the delimited strings

This an optional argument.

and CANCHECK option not specified.

Code	Meaning
0	Selected_value equal to one of the delimited strings.
2	Selected_value not equal to any of the delimited strings,
	Any other error results in cancellation of the User Language request.

$WEB_SELS_CHECK return codes

For example, the following statement will cancel the User Language request if the value of variable %SEL is not one of the stringsDN0, DN1, etc.:

%RC = $Web_Sels_Check('/DN0/DN1/DN2/DN3/DN4' - WITH '/DN5/DN6', %SEL, 'CANCHECK')

See $Web_Selp for an extended example using other $WEB_SELx functions.
