Where are these datasets under Easytrieve release r11.x? Are they needed?
Dataset CAISRC is obsolete for R11.x.
The OPTENV and OPTTBL members are now found in the CAIMAC library for release 11/11.5 and in the ABAAMAC and CBAAMAC libraries for release 11.6.
You do not need INDMAC, INDOBJ, INDSRC libraries for R11x. No equivalent datasets are needed.
