Error in specifying a string
In input fields that require a string, you must specify the string in the manner required by the format that you have selected for the macro, either the basic macro format or the advanced macro format (see Representation of strings and special characters, treatment of operator characters).
For example, if you have selected the advanced macro format, but you specify
a string that is not surrounded with single quotes (such as Terminal
parameters), then the Macro Editiro will display an error message like
the following:
String -- Invalid expression -- Resetting to previous value.
To avoid getting this error message, specify the string surrounded with
single quotes (such as 'Terminal parameters'). In contrast, if you have selected the basic macro format, but you specify a string that is surrounded with single quotes, then you will not get an error message, but the Macro Editor will treat the single quotes as part of the string.
