Passing parameters doesn't have a practical limit. The following works without problem:

clear
x = REPLICATE("abc", 100000)
function_a(x)

FUNCTION function_a(tcpar)
	? LEN(x)
ENDFUNC

(Length of parameters = 300,000)

In any case, it is worthwhile to try to check each aspect separately, e.g., parameter passing, macro expansion, SQL command.

For example, you can build the entire SQL command - you don't even need macro expansion for this - as a string, and then execute it all at once. For example, if the list of fields is variable:

lcCommand = "select " + lcFieldList + " from MyTable"
&lcCommand
