expand variables and functions with the string s. The optional level parameter specifies how much to expand. If omitted or zero, the argument is recursively expanded until it doesn't contain anything left to expand. To expand the string N times, use the number N as the level. For example %expand(s,1) only expands the string s one time.
If level is -1, the <> and  syntax is expanded only. If level is -2, the string is expanded as a trigger pattern (which changes the meaning of the  characters for example). If level is -3, the <> syntax is expanded for a trigger pattern.
