F_BA_CompareVersion

The function F_BA_CompareVersion of return type BOOL compares two version numbers stVersion1 and stVersion2, each of type ST_BA_Version. The input variable nLimit specifies how many digits are to be compared, starting with 1 = "Major". The enumeration eCompare specifies the comparison operation. The function return value changes to TRUE if the comparison is fulfilled.

For example, if stVersion1 is lower than stVersion2, then the comparison eCompare = E_BA_CompareMode.eLower returns a TRUE as function return.
