passing a CL command string as a variable (a call command)

I am trying to get my group job to spawn....

my RPGLE program does:

// Commnd = CALL XYZ9CL PARM(' ' ' ' X'000F' X'00000F')

Commnd = %xlate(AP:QUOTE:Commnd) ;
// turn the single quotes to double quotes....
cmmnd = 'CHGDTAARA DTAARA(*GDA) VALUE(' + AP +
%trim(Commnd) + AP + ')' ;
#ExcCmd(%trim(cmmnd)
:%Len(%Trim(cmmnd))) ;


so when I get to my CL program that reads the *GDA, it doesn't like
the double quotes...... and I can't find a way to %xlate the quotes in
CLLE...

it seems like I am doing it wrong in the RPG turning the single quotes to
double quotes?

any ideas???
