Select the block you want to copy by pressing F2 at the top of the block, scrolling down and pressing F2 at the bottom; this highlights the block.
Now press F1 to bring up the editor and scroll sideways until you find the drop down menu that show "Copy to Clipboard". Scroll down to select this and press Write; now you block is copied to the clipboard.
Now open the program you want to paste it into and scroll down to where you want it to insert. Then press F1, find the Clipboard menu, scroll down to "Paste from Clipboard" and press Write.
I just realised the IPS writes programs in MDI (I think) so you have to convert this to a program. Type in a program name; Onnnnn where nnnnn is a number that has not been used yet. Then press Alter and that will make your MDI program go into memory under that name.
An open mind is a virtue...so long as all the common sense has not leaked out.
