1559	Array indexing inside a function	asodja	asodja	"In the attachment are three variations of the same function (whithout change of functionality) gives three different errors.

1. When identifier 'end' is used as index (in example SimpsonTest_1.mo), the following error is printed:
{{{
[SimCodeC.tpl:4220:14-4220:14:writable] Error: Template error: Unknown expression: end
}}}

2. When first the value of {{size(vals,1)}} is assigned to a variable (in example SimpsonTest_2.mo) and then the variable is used for indexing is the error:
{{{

}}}

3. When a call to {{size(vals,1)}} is insert directly in array subscripts (example SimpsonTest_3.mo), the error is:
