The template refers to values in the String table by using the STRING keyword followed by the name whose value is desired. The value will replace the STRING keyword.
#strings_sp.properties
btnYes=Si
btnNo=No
{! Confirm.inc }
{STRINGTABLE strings}
<FORM Method=put Action="...">
<INPUT Type="submit" Name="Yes" Value="{STRING btnYes}">
<INPUT Type="submit" Name="No" Value="{STRING btnNo}">
</FORM>
This example would generate the following HTML text:
<FORM Method=put Action="...">
<INPUT Type="submit" Name="Yes" Value="Si">
<INPUT Type="submit" Name="No" Value="No">
</FORM>
