Thanks a lot for sharing the interesting read.

Quote:Since you had to press the “loop” steps yourself by
pressing the same sequence of keys over and over
again it became a challenge to work out the most
efficient stack manipulation sequence possible to
reduce the number of loop keys to press.

Appendix E – TI SR50 Competition, HP Analysis

WHAT THE SR-50 DOES HAVE

[d/r] key - converts degrees to radians and radians to degrees depending on position of D-R switch.
This operation can be accomplished on the HP-35 by the following:

Convert degrees to radians:

DATA [ENTER↑] 180 [ENTER↑] [\(\pi\)] [÷] [÷]

Convert radians to degrees:

DATA [ENTER↑] 180 [ENTER↑] [\(\pi\)] [÷] [×]

The same could be accomplished without using the [ENTER↑] key:

Convert degrees to radians:

DATA [\(\pi\)] [×] 180 [÷]

Convert radians to degrees:

DATA [\(\pi\)] [÷] 180 [×]

So why wouldn't they propagate the shorter solution?
