You can do most of this by using a login.sql. login.sql is executed during - surprising - login and is loaded from your SQLPATH or current directory. For the examples you gave, your really chose the worst case.
Problem is the sqlterminator. Whatever you put in there, the forward slash is maintained as a free sqlterminator. Next to that, sqlplus first scans for the sqlterminator and does this before scanning to the string terminator. A bug if you ask me. The forward slash can be used in a string as long as it is not alone on a seperate line. As soon as sqlplus finds the character specified as sqlterminator, it ignores everything else and stops reading.
The forward slash can be handled, as long as it is not alone on a line.
login.sql contains:
prompt run login.sql
show sqlterminator
show sqlblanklines
set sqlblanklines on
set sqlterminator ';'
show sqlterminator
show sqlblanklines
prompt ready login.sql
set echo on
leigh.sql contains:
INSERT INTO t1 VALUES ('fail bc semicolon
a;a
/
');
INSERT INTO t1 VALUES ('fail bc solo /
aa
/
');
INSERT INTO t1 VALUES ('ok / not solo
aa
/a
');
DELETE FROM t1 WHERE a = 'c
a/
';
run the script:

No need to fiddle with begin/end blocks. Can't handle sqlterminator inside command, no matter where it is, in a string or not, can't handle lines with forward slash alone on a line in a string.
You could execute each script using a separate call to SQLPlus and have them run in the background.
If you just need to remove errant parameters you could search for them in the scripts and not run those scripts that contain un-supplied parameters.

Try it like this:
(See http://www.orafaq.com/forum/mv/msg/80574/233106/0/#msg_233106)
Bottom line is that retCode must be a variable defined in SQL*PLUS's scope. Your DECLARE is inside a code block, and SQL*PLUS can't see into it.
