In an ABAP/4 (client) program, you can use the ABAP/4 Dictionary structure CPICCONN. Set the data
and then send the logon string with COMMUNICATION SEND.
In a C program, you first set up the logon string with SAP_CMLOGON and then send it with
CMSEND. The logon string is appropriately formatted and converted from ASCII to EBCDIC because
a logon string is expected in EBCDIC both for R/2 and for R/3.
