Alternative to CPYF that doesn't apply a lock

Hi List

We have a program that makes use of the CPYF command to copy data from a work file in QTEMP to a corresponding file in our data library. Depending on the file being used there can be upwards to 100,000 records being copied which is starting to cause a problem as the CPYF applies a lock to the file being copied into.

The help text describes the restriction as:
o During the time a CPYF request is run, the file specified for
the To file (TOFILE) parameter may be locked (similar to an *EXCL lock with no timeout) so that no access is possible.
Because the file is locked this is causing other programs to fail CPF4128 and RPG1216 errors. I am thinking about putting in a change to use an SQL insert instead of the CPYF and was wondering if anybody knows whether or not using SQL would apply a lock to the receiving file.

Thanks in advance

Jonathan
