I’ve seen that a new help file has been published on December 19 with a fix for [∑REG] and [∑RG?].
I’m wondering if this is the right topic for comments, or if a dedicated topic would be better (I’m not sure Scotland or Texas related discussions as interesting as they are, can improve the help content) … anyway, here they are:
In addition to ÷ and × the calculator's glyphs for the ▲ and ▼ character codes are also transposed throughout the Help browser.
In the DM42 Functions list:
BASE* should be BASE×
BASE/ should be BASE÷
ClALL should be CLALL
ClΣ should be CLΣ
RCLX should be RCL×
RCL+ should be RCL÷ for Recall divide
In Setup Menu → File under Activate USB Disk:
Perpare should be Prepare
Maybe be it would good also to add in the help the hidden matrix functions [MIN], [MAX] and [FIND].
