error -1200

Hi, I am getting error -1200 = Number is too large for a DECIMAL data type. Is there a way to store a very large number?. Using i4gl, Version 4.10 on SunOS. Real world is: -------------- FUNCTION find_gos(of,cr) DEFINE of DECIMAL, cr INTEGER, x,y DECIMAL(32,32), i INTEGER, cc DECIMAL #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # The for loop fails if # of > 314.2 # cr > 190 #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ let x = 1 let y = 1 FOR i = 1 to cr LET x = x * of / i LET y = x + y END FOR LET cc = x / y RETURN cc END FUNCTION Any help??
