i need to output letters using the position() function

i need the syntax to output an "A" using the ascii number value

for example:

ascifunction(x + position())

where x is the number of the letter "A" minus 1

XML uses Unicode, not ASCII.

You can't get the Unicode code for a character in XSLT 1.0. In 2.0 you can use the functions string-to-codepoints() and codepoints-to-string(). Alternatively your needs may be met by <xsl:number value="position()" format="A"/>.
