Joe,

A string constant is limited to 255 characters:

lcStr = "there can not be more than 255 characters in here ..."

A string memvar is limited only by memory.

lcStr = replicate( "abcde", 10000 )
? len( lcStr )

Don't macro expand your string, and parse it apart in your function.

nReturn = MyFunc( table.memo )

function MyFunc( lcStr )
local laItems[1], i, n

n = alines( laItems, chrtran( lcStr, ',', chr(13) ) )
for i = 1 to n
   ... do something to each item
endfor

>I'm working in a VFP 5.0 application and attempting to assign a table's memo field to a string, which I then pass along to one of my form's procedures using the following command:
>
>nReturn = (&lcBEFORE)

>where lnBEFORE is my memo field, and in which nReturn is a numeric value returning either the MIN, MAX or AVG of the string of values (separated by commas) I've passed to the procedure. The procedure is working fine except when I have more than 255 characters (sometimes it's 300+ characters).
