Easiest groups/lineages of machines to port software between?

[Thomas Klemm]

From item 20 of the HP-35s bug list:

Quote:Solve infinite loops for some program based functions. Assign FN=D and SOLVE the following for X. The solve doesn't finish. This seems to be related to using a loop in the function being solved.

Code:

D001 LBL D
D002 10
D003 STO N
D004 DSE N
D005 GTO D004
D006 RCL X
D007 COS
D008 RTN

A workaround for this is to include an always false conditional after any INPUT statements with a RTN instruction and a STOP. For example:

Code:

B001 LBL B
B002 INPUT T
B003 INPUT X
B004 CF 1
B005 FS? 1
B006 RTN
B007 FS? 1
B008 XEQ C001
B009 0.2xX-T
B010 RTN
C001 LBL C
C002 STOP
C003 RTN

Not sure how this workaround should be applied to the example above.

Cheers
