CAS command question

[DrD]

Parisse,

I KNOW IT'S a CAS process, required as a result of evaluation of the inequality symbol. I don't disagree with you on this point. That isn't the issue. Forget about ANY relational operator, (<, =, >), they're NOT the reason for this issue. I totally understand that CAS evaluates the expression.

Where we are disagree is before the relational operation ever enters into the discussion. We have beat this issue to death, but commands, like the CAS coeff(), command, want an expression as an argument. To get an expression, *without* evaluation, (I KNOW IT GETS EVAL'd BY CAS!), from the appropriate left or right side, it must be separated from the relation, into the corresponding expression. Then, as in this example, coeff(Expr,[Var], [Integer]), and many other commands that take expressions as arguments, they are perfectly happy.

I know there are extra preparation work-a-rounds. I know you have a offered a helper program. The specific program I made is working just fine with my own work-a-round. It's not about getting a program to work ... it is about satisfying other commands likely to be part of ANY working program, that need expressions separated consistently. Then users can supply a list of relations, and they will pass through any set of similar commands without need of further left/right expression exchange.

There isn't any further point in discussing this. I see it as a bug, you don't, we disagree. I will be glad to buy you a beer, coffee, your choice, and personally thank you for all of your contributions over time; but we simply disagree on this one. Ignoring my posts (Only on this one issue, of course!), was a great idea!
