GT_ASCPOS()

Return the ascii value of a specified character in a string
---------------------------------------------------------------------------------

 Syntax

        GT_Ascpos(<cStr>, <nPos>) --> nAscVal  

 Arguments

        <cStr>    - The string <nPos>  - The position in <cStr>     

 Returns

        <nAscVal>   - The ascii value of substr(<cStr>, <nPos>, 1)    

 Description

      Return the ascii value of a specified character in a string
      Equivalent (but much faster) to  asc(substr(cStr, nPos, 1)

      NOTE:  invalid parameters will return -1  nPos > len(cStr)   will
      return -2

      This last behaviour is different to the Funcky function of the  same
      name.  I changed the behaviour because some of the strings  I
      process contain embedded NULs.

 Examples

       ? gt_ascpos("the cat sat on the mat", 3) // prints e

Status

      Ready
