Function "contains" in HOME and CAS

[cyrille de brébisson]

Hello,

home contains(L1, "A") will cause A to be parsed as a CAS command line before the switch to CAS mode and the execution of contains. Assuming that the var A contains 0, what you execute is: contains(L1,0).
CAS(contains(L1,"A")) will not cause a parse of the string.

Subtelties of HOME/CAS interraction :-)
