Main Index Predefined Functions

user defined functions

Functions are defined using the function statement
[...] = optional ... = your value
function_name[ $first_var=...; $more_vars=... ; $last_var=...]
[...]
endfunction
[var $... = ]call function_name[ $first_var=...; $more_vars=... ; $last_var=...]

Notes

Functions can be defined in the current script
or in a .xt file stored locally or anywhere on the web.
Functions can also be called from html
The Function must be defined in a Xtscript on the same page
or included from elsewhere
<xt:call function="..." first_var="..." more_vars="..." last_var="..."/>
or like this
<xt:call function="..." args="$first_var=...;$more_vars=...;$last_var=..." />
