The XMCQDPT code is very flexible so you can dramatically
reduce memory needs using additional keywords in the $xmcqdpt
group. Please let me know if you need some help with this.

Regardless on your initial question, it's very bad idea to set micit to 200.

edshft=0.2 is the really HUGE shift. The recommended value is 0.02. Note, this is ISA shift (that is similar to imaginary shift), not
the plain denominators shift (0.2 would be OK with plain shift).
