I have never worked with the _insertmem and _delmem commands, so I cant help 
you there, but I may be able to provide an alternative. If all you need is 
some extra Ram space, then you may just want to create an external program 
with the desired size you want, and delete that prog later, instead of 
messing with the size of your prog... Unless you are doing this to experiment 
and learn how to resize a prog, I wouldnt know how to do that, I dont see 
myself ever using such a concept though, possibly writing an oncalc assembler 
that has to resize the source prog constantly, but we'll see later... Sorry I 
couldnt be more of help... cya.
