6.12 Global Print Options (GPRINT/NOGPRINT)<br />

Global print options can be set using the GPRINT command outside the individual programs<br />

(the first letter G is optional, but should be used to avoid confusion with program specific PRINT<br />

cards). The syntax is<br />

GPRINT,key1[=value1],key2[=value2],. . .<br />

NOGPRINT,key1,key2,. . .<br />

Normally, value can be omitted, but values > 0 may be used for debugging purposes, giving<br />

more information in some cases. The default is no print for all options, except for DISTANCE,<br />

ANGLES (default=0), and VARIABLE. NOGPRINT,key is equivalent to PRINT,key=-1. key<br />

can be one of the following:<br />

BASIS<br />

DISTANCE<br />

ANGLES<br />

ORBITAL<br />

ORBEN<br />

Print basis information<br />

Print bond distances (default)<br />

Print bond angle information (default). If > 0, dihedral angles are<br />

also printed.<br />

Print orbitals in SCF and MCSCF<br />

Print orbital energies in SCF
