You need to make your entire error message into one string. This is easy to do in GAUSS with the $+ operator which merges the contents of two strings together like this:

stringA = "GDP";
stringB = "Inflation";
stringC = stringA$+stringB;

Now stringC will equal: “GDP Inflation”.

For your example, this will work:

if ret;
   errorlogat "Matrix "$+myVar$+"is not invertible";
endif;
