#36 undesirable feature when using conv_strToXXX

[David W. Zavitz]

// an undesirable feature ... when
// entering numbers via string input first

// if '1234567' is entered in the first loop, and
// then just an empty line entered on the next loops,
// the program prints out '567' each loop
// (and doesn't throw any exception)

// tested with HLA 1.101 and 1.102
// with Win XP 2008-04-29

"mystrTou32.hhf" handles two problem cases
