Пробую:

println(wv_set, '.zoomBy(', Float(DefaultFontSize),');')

Ошибка всегда одинаковая:
[javac] C:\HiAsm_AltBuild\Elements\android\code\result\src\hiasm\hiasmproject\HiasmMain.java:36: error: cannot find symbol
[javac] wv_set2.zoomOut ();
[javac] ^
[javac] symbol: method zoomOut(int)
[javac] location: variable wv_set2 of type WebSettings
