Single Value Variables

If a variable always resolves to a single string, use the variable directly without modification in the FlexConfig script.

For example, the predefined text variable tcpMssBytes always resolves to a single value (which must be numeric). The Sysopt_basic FlexConfig then uses an if/then/else structure to set the maximum segment size based on the value of another single-value text variable, tcpMssMinimum:

#if($tcpMssMinimum == "true")
  sysopt connection tcpmss minimum $tcpMssBytes 
#else
  sysopt connection tcpmss $tcpMssBytes 
#end

In this example, you would use the Insert menu in the FlexConfig object editor to add the first use of $tcpMssBytes, but you would type in the variable directly on the #else line.

Secret key variables are a special type of single value variable. For secret keys, you always use the Insert menu to add the variable, even for second and subsequent uses. These variables do not show up in the Variables list within the FlexConfig object.
