I think others answered your question, but can I suggest something? If you're going to use Hungarian Notation - please wait whilst I retch into my trash can <g> - you might want to look at that parameter statement:

LPARAMETERS lcCxfer, lcOS, llDoAlloc

Parameters are often given a different prefix, to differentiate them from local variables (lcName, lcState, lnDegeneres). "t" (PARAMEtER) seems to be popular, so your parameter statement would be:

LPARAMETERS tcCxfer, tcOS, tlDoAlloc
