“checkdbsel”: check whether the value of a parameter in a file is “selected”
Returns the “selected” string if the value of the parameter contained in the file indicated by the tag is the same as indicated in the tag itself, otherwise it returns
an empty string.
SYNTAX
<%checkdbsel('Filename', 'ParameterName', 'Value')%>
Used in the construction of drop-down menu with the html “select” command, selects the current value of the parameter.
Example (
Figure G.g
)
With reference to the ‘commcfg’ configuration file already seen for the previous tags; a drop-down menu is created similar to the one used on the configuration
page shown in on page 46, so as to allow the selection between the values 9600, 19200 and 38400; if the parameter in the file is equal to 19200, the menu
will show that value as already being selected.

Figure G.g - The “checkdbsel” TAG: example
“checkdbradio”: check whether the value of a parameter in a file is “checked”
This works in exactly the same way as <%checkdbsel%>, but returns "checked=”checked”" instead of “selected” and is used for "radio"
buttons, that is, those buttons in which one selection excludes the others.
