I wrote a quick test program to lock a record. When I run it the first time, no problems. When I run it a second time, I get RNX1211 - I/O operation was applied to closed file PFDLRREPS. Why?

**free

/if defined(*crtRPGBND)

ctl-opt actGrp(*new) dftActGrp(*no);

/endIf

ctl-opt main(entry) option(*noDebugIO);

dcl-f pfDlrReps keyed usage(*update);

dcl-proc entry;

dcl-pi entry extPgm('T_REP_LOCK');

dealer char(6);

end-Pi;

dcl-s response char(1);

chain dealer dealerReps;

if %found();

drAuth = 'lock';

dsply 'Rec locked until you press enter' '' response;

update dealerReps;

endIf;

close pfDlrReps;

end-Proc;

Found it!!! Look back at the code on the second line. I keyed *crtRPGBND instead of *crtBndRPG. Because of my typo the file was opened/closed in the default activation group. Works like a charm in a *new activation group :)
