Frogbit style syntax in textpipe

[Aircut]

in the 90's there was a british company who came up with a text manipulation tool which i found very useful. and i am still running it on a windows xp platform.
the main benefit of frogbit is that you can create if...endif and while..endwhile clusters and basically program a complicated script that will make unlimited passes to a source file,

if anyone is familiar with frogbit, is there a way migrate from old frogbit code to textpipe?
