Hi,

I use an HP 49G calculator. I have three problems.

#1 I try to create a directory in the HP 49G's port memory 0 & 1. The HP 49G won't let me do the. The puropose of the directories is to store my programs and equations on those ports. is there a correct procedure to do this?

#2 I try to cut, copy, & paste on my equations on equation writer, and on the command line. The HP 49G won't let me do that. Is there a correct procedure to do that?

#3 I used the equation solver for the HP 49G. The equation is q = k*(Pn)^1/2, where k is in units of (GPM/(psi)^1/2), q is in GPM, and Pn is in psi. (GPM stands for Gallons per Minute).

I tried to incorporate the units into my HP 49G solver. The problem is that when I try to to type into the k "1_gal/(min*(psi)^(1/2))", the HP 49G responds by saying "Invalid Syntax".

Please help me correct this problems.

Thanks in advance

Mark
