This is how I have coded

Chnlanalp usage(*output:*update) keyed prefix('CHA.');


dcl-ds CHA Extname('CHNLANALP') qualified end-ds;

Then I can read or chain WITHOUT mentioning CHA
Read CHNLANALP;

This will populate CHA data set


Not really. You're tricking the compiler -- not recommended for
clarity to those who come later. You should not use a prefix with a
period in it. A DCL-F without the qualified keyword will create I-specs
for the I/O area. I always use the qualified keyword on the DCL-F to
avoid creating I-specs.


​Not sure it's tricking the compiler....I seem to recall this technique
being documented by IBM originally....
