Hello again Leonardo, I just found this.... https://www.ibm.com/support/knowledgecenter/SSSH27_8.0.1/com.ibm.rational.clearcase.cczose.doc/topics/r_cce_ibm930.htm
The first paragraph reads: *Because IBM-930 does not support lowercase alphabet characters, TSO client does not support them either.* So, I guess IBM-930 just does not provide support for lowercase alphabetics.
