If I may: 'resolving' generally refers to the act of looking for a program
via the library list, converting it's address into a pointer and then
invoking it.  If you specify the program name as a literal: CALL 'BUCKPGM',
then the program is resolved the first time the CALL opcode executes.  That
means that if you replace the program while the caller executes, you won't
see the new copy; the pointer will be pointing to the oddly named program
object in QRPLOBJ:

CALL 'BUCKPGM'
do some more stuff
 (compile BUCKPGM, REPLACE(*YES))
do some stuff
CALL 'BUCKPGM'

You can have RPG re-resolve the program if you use a variable for the
program name: CALL PGM.  You can also have RPG re-resolve if you FREE it:

CALL 'BUCKPGM'
do some more stuff
 (compile BUCKPGM, REPLACE(*YES))
do some stuff
FREE 'BUCKPGM'
CALL 'BUCKPGM'
