PNut_v50 has several new features and fixes a bug introduced in PNut_v49 that caused structure sizes to be wrong. Here's what's new in v50:

• New DEBUG PLOT commands allowing up to 8 bitmap layers that you can selectively copy into the PLOT window. This is useful for doing photo-realistic displays, where pre-drawn images are copied into the plot window to show, say, a toggle switch being in an ON or OFF position.

• New DITTO directive for DAT blocks and inline PASM sections, which can iteratively generate code.

• ORGH is now available for inline PASM code in PUB/PRI methods. ORGH has the same usage syntax as ORG, but executes PASM code in-place from hub memory, without loading it into register space.

• New @(backslash)"string" method is like @"string", but allows escape characters like (backslash)n (new line, 10) and (backslash)xFF (hexadecimal values).

• Predefined registers, like PR0, DIRA, OUTA, and INA, can now be used in CON block expressions.

• PASM DEBUG instructions can now be expressed with a conditional prefix, like 'IF_C DEBUG'. This is accomplished by placing an opposite-condition 'SKIP #1' before the DEBUG (BRK) instruction.

New PNut_v50p1 allows structure longs to act as method pointers. Also, when specifying the number of return parameters for a method pointer, the colon can be followed by a either a CON-STRUCT name for size or a constant (as has been the case).
