Variable storage types changing from wave to wave

Data inconsistency

I wanted ask whether it would be possible to ensure that data storage types for a given variable not change from wave to wave. For example, in the Special Licence Stata data I am using, w_jshrs changes from type 'int' in wave E, to 'float' in wave F, to 'byte' in wave G. While this doesn't matter for most analysis (e.g. Stata analysis), it does matter if you are trying to read the data into a programme that is more specific on data types. If it is not possible to keep them consistent, it would be very useful to have a list which details every variable which changes type over the survey. Apologies if that is already available and I can't find it.

(I downloaded the data I am using December 2018, which may not be the very latest version)

Many thanks,
