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
