Return to Tag List
 
The DEFSET tag is used to set a variable to a value, if a value has not already been associated with it. The tag is the short form of:
   <SAIF COND=!IsDefined(var)>
      <SASET NAME=var VALUE=value>
   </SAIF>


If the variable already has a value (not an empty string), the variable will remain unchanged.
 
Attributes:
NAMEvariable name
VALUEvariable or expression

 
The following is an example of DEFSET;
 
<!--- Will create 'var' with the below value --->
<SADEFSET NAME=var VALUE="var will now be this string">

<SASET NAME=var2 VALUE="var2 value">

<!--- Won't do anything since var2 has a value --->
<SADEFSET NAME=var2 VALUE="var2 will not be this string">
