Does anyone know where the allowable length of host variable names is documented for Pro*C? We've upgraded a database from 8.1.7 to 10.2.0.5 (HP-UX). After recompiling pro*c, developers are stating that programs are not behaving properly unless some variable names are shortened. Examples of what they're telling me they had to change: original variable name changed variable names char flt_cd_prc_clss_copics[3]; char flt_cd_clss_copics[3]; char flt_cd_clss_grp_sls[3]; char flt_cd_cls_grp_sls[3]; I'm finding this difficult to believe, but I suppose it's theoretically possible. I'd still love to find where (if anywhere) this is documented. Matt
