Notes
IsAlpha returns TRUE if the first character of sString is an ASCII alphabetic
character (in the range a through z or A through Z); otherwise it
returns FALSE.
IsAlpha emulates the application of the C library function
iswalpha on the first character of a specified string. IsAlpha is
locale sensitive.
Example
Print(IsAlpha("hello")) // prints: TRUE
Print(IsAlpha("123")) // prints: FALSE
