HP Prime: CAS Commands in Home Mode

[cyrille de brébisson]

Hello

Quote:Inside the program, you cannot write something like CAS("subst(k, X='x')"), because nothing gets substututed, (only returns k), so you can't use the function with lower case 'x' for further processing with CAS commands/functions.

HAve you tried using
subst(k, "X='x'"); ?
this would cause numerical mode to send the value of k and a CAS compiled "X='x'" to the CAS subst command...
