character value

[shulbert@littlejohnfrazer.com]

you have to redefine a character item as an integer.

you can do this in the dictionary (see the pdl documentation: "redefined by") but you can also use subfiles. as long as the length is the same PH doesn't care what record layout you append.

as an example:

first define a one byte subfile record:

	cancel clear
	def a integer unsigned size 1 = 0
	set sub
	rep sum a
	go

then append to this the character value:

	cancel clear
	def b cha = "A"
	set sub append
	rep sum b
	go

this should give you the ASCII value on the second record.

this has only been tested on AIX and SCO but i think the logic will work elsewhere.

on systems that have a two byte minimum, both the items should be size 2, and quiz will append a space to the character item. so to remove the value of the space (ASCII 32) you have to either subtract 32 and divide by 256, or subtract 8192 depending on whether the first bit is most or least significant.

Does anyone know of a way in quiz to get the ASCII value of a single character returned as a number?
I know how to get from a displayable character from an integer, I need to go the other way.

For instance if a variable contains the letter "A" I would like to be able to that converted to the number 65.
