/* Example: */
/* CALL PGM(REGPUBKEY) PARM(CERTFILE) */
/* */
/* */
/* Note: This program assumes the card with the profile is */

/* The Common Cryptographic Architecture (CCA) verb used is */
/* PKA_Public_Key_Register (CSNDPKR). */
/* */
/* Use these commands to compile this program on the system: */
/* ADDLIBLE LIB(QCCA) */
/* CRTCMOD MODULE(REGPUBKEY) SRCFILE(SAMPLE) */
/* CRTPGM PGM(REGPUBKEY) MODULE(REGPUBKEY) */
/* BNDDIR(QCCA/QC6BNDDIR) */
