If *value*=0, the corresponding threshold is set to zero, otherwise
10**(-*value*). The equal signs may be omitted. If no codes are
specified, the default values are printed. The following codes are allowed
(max 7 per card):

`ZERO:`- numerical zero
`THRDLP:`- delete pairs if eigenvalue of overlap matrix is smaller than this threshold.
`PNORM:`- delete pair if its norm is smaller than this threshold (all pairs are normalized to one for a closed shell case).
`PRINTCI:`- print CI coefficients which are larger than this value.
`INTEG:`- omit two-electron integrals which are smaller than this value.
`ENERGY:`- convergence threshold for energy; see also:
`ACCU`card. `COEFF:`- convergence threshold for coefficients; see also:
`ACCU`card. `SPARSE:`- omit coefficient changes which are smaller than this value.
`EQUAL:`- set values in the internal vector and the diagonal elements equal if they differ by less than this value. Useful for keeping track of symmetry.
