Variables with a , in the variable label, such as Milage, mpg, is allowed in Stata but will make the data points for that variable be shifted one column in the data table.

The csv solution for that would be to enclose all cells in double quotes. Such as mpg,Milage , mpg,byte,74 becomes "mpg","Milage , mpg","byte","74". However, then all strings needs to be compounded `" "' strings. And also, these extra quotes should not be added in the .md format.

The way I avoided that in iebaltab was to write a tab separated temp file I imported to Stata as a data file and then used Stata native features to export to csv that takes care of this. Not sure if that is the best approach here as the header is different and there is no equivalent for .md.

Another approach is to no mix code that generates the data point with code that outputs. If the data point code just create all values then some other code can specialize in output. In the current version of iesave in #276 the code is structured the same way as the old approach in iebaltab. iesave is likely to not be as complex so it could be ok, but maybe worth trying to avoid.

Both the csv and the md output is structured enough that this should be possible to be abstracted away in some functions. The best approach would be if Stata had support for lists or arrays.
