SQL select can go up to 2000+ characters, but you should probably build up a text-string variable instead of merging and compiling a .prg. It will perform better as well. Ex.:
lcSel = "SELECT "
lcSel = lcSel + "SomeFields" + " FROM "
lcSel = lcSel + "SomeTables" + " WHERE " 
lcSel = lcSel + "Condition"
&lcSel
I do it that way and it works great.
