concatenate ints with cons chars

hi

i trying print following on 1 line

code: [select]

serial.println(',,' += mapped_aux1 += '/' += mapped_aux3 += '/' += mapped_gear += '/' += mapped_flaps += '/' += wf_c += '/' += wf_wl += '/' += wf_fuf += '/' += lg_ud += '/' += lg_doors += '/' += lg_bof += '/' += cf_pos += '/' += cf_am += '/' += e_temp += '/' += e_choke += '/' += e_imomb += '/' += e_starter += '/' += c_oc += ',');

mapped_aux1, etc integers.

however following error when compiling,
serial_coms:159: error: lvalue required left operand of assignment

if use "/" instead of '/' following,
serial_coms:159: error: invalid conversion 'const char*' 'int'
serial_coms:159: error: assignment of read-only location '",,"'

i know can using

code: [select]

serial.print(",,");
    serial.print(mapped_aux1);
    serial.print("/");
etc, serial.println @ end. 
however can cause problems vb program creating arduino communicating if arduino starts printing half way down line when port first opened.

any or ideas appreciated.
thanx

some research on sprintf() and/or snprintf() functions pay dividends you.
