Character definition for data set elements naming

Character definition

We recommend to use only alphanumeric characters and the underscore “_” character in the strings of your data set.

Unfortunately, in the Monolix2016R1 suite, special characters such as spaces ” “, stars “*”, parentheses “(“, brackets “[“, dashes “-“, dots “.” and slashes “/” are not supported in:

  • The headers
  • The strings in CAT column.

This feature will be back in the next release.

Please be careful that if your data set includes unsupported characters, the error will only de detected and displayed when loading a saved project (and not when creating and saving the project).

On the use of “.”

The “.” can be used in almost all the lines of the data set but has several meaning depending on the context. The following table summarizes the use of it.
