 +**VR10AscToUWr (array, index, return, errcode)**
 +
 +Parameters:
 +
 +^IN/OUT^VARIABLE TYPE^EXAMPLE NAME^DIM^^
 +|  IN  |  ARRGBL  |  array  |  B  |Array containing the data to be converted (must be declared with at least "index + 3" items)|
 +|  IN  |  GLOBAL  |  index  |  L  |Index of the array element at the beginning of the data|
 +|  OUT  |  GLOBAL  |  return  |  L  |Data value converted|

 +array[1] = 68
 +array[2] = 56
 +array[3 = 51
 +array[4 = 50
 +
 +VR10AscToUWr (array, index, return, errcode)
