Simplex Program

Hi Leo,

It seems that the CAS program doesn't work on your calculator.
You are using virtual or real calculator? (Virtual calculator always corrupt cas vars memory everytime I turn it on)
If you are using virtual calculator, please press SHIFT MEM("B").
Then press CAS Vars and delete all CAS functions and variables.
Then press SHIFT program, edit sim20_11 and then press check.
It should display "No errors in the program", then OK, ESC and ESC.
Then type sim20(99) in CAS mode again.

If it still doesn't work, please check the CAS setting.
It should be same as below picture.
   

Regards,

PS. This program work fine in my virtual Cal and real Cal except the corrupt issue of virtual Cal.
