Missing typecast on MinSize and MaxSize

[osresearch]

MinSize and MaxSize are printed as characters, not ints:

0x1A04E4                        String: Local IP Address, 
 VarStoreInfo (VarOffset/VarName): 0x2, 
 VarStore: 0x1, 
 QuestionId: 0x102, 
 MinSize: 0x^G, 
 MaxSize: 0x^O
 {1C 90 08 00 09 00 02 01 01 00 02 00 04 07 0F 00}

Should the types be unsigned or something more specific?
