Hello, with the following test-file I expect the output: "Yes No" But the output is: "edef @@lycurrentstate{myTestbla}No edef @@lycurrentstate{myTestblub}No" Where does this come from, and how could I get it right please?

\def\myMacro#1{\doifdefinedelse{myTest#1}{Yes}{No}} \def\myTestfile{\jobname-test.tmp} \def\myTestbla{just a test} \starttext \immediate\write18{echo \myMacro{bla} \myMacro{blub} >\myTestfile} \typefile{\myTestfile} \stoptext

Greetings, Peter
