SqlPlus error messages are daunting, aren't they?

Question

Hello guys,
I am trying to understand the logic of SQLPLUS error messages. I read the User's Guide and Reference but I still don't understand how these line numbers are calculated!!
I make an example. I am writing some stored procedures in a file merge_procedures.sql, that I am editing in my favourite text editor (Crimson editor). Beside, I have SQL Plus running in a dos windows in XP.
The file defines 2 packages and various procedures and functions.
CREATE OR REPLACE PACKAGE STRING_FNC
AS
END STRING_FNC;
CREATE OR REPLACE PACKAGE BODY STRING_FNC
AS
END STRING_FNC;
CREATE OR REPLACE PACKAGE moveSections
AS
end moveSections;
When I run one of the procedures using EXEC procName(args) I get an error:
SQL> EXEC moveSections.mergeUserSections('EMPTY_jbowerstest','A01','XC','G201','
*01.G1','G101','01.G1.G1')*
BEGIN moveSections.mergeUserSections('EMPTY_jbowerstest','A01','XC','G201','01.G
*1','G101','01.G1.G1'); END;*
ERROR at line 1:
ORA-00001: unique constraint (DEV_XCSA.SYS_C008826) violated
ORA-06512: at "DEV_XCSA.MOVESECTIONS", line 68
ORA-06512: at "DEV_XCSA.MOVESECTIONS", line 88
ORA-06512: at "DEV_XCSA.MOVESECTIONS", line 156
ORA-06512: at line 1
I don't understand how those line numbers are calculated. I mean, why does it claim there is an error at line 1? And how are the subsequent line numbers calculated? i am getting lost since I cannot find any error at the lines indicated.
Please help me. Also references to documentation would be appreciated.
Thanks
TN

Like Danny, I find it helpful to read messages like this from the top down.
The stack above says that the real error, ORA-00001, occurred at line 68 of movesections.
The procedure at line 68 was called from line 88 of movesections. The real error may have occured around this point; for example, if you passed a bad parameter at line 88, then the code around line 68 may be perfect.
The procedure at line 88 was called form lline 156 of movesections. Again, the real error may be at line 156, or somewhere leading up to line 156.
The procedure at line 156 was called from line 1 of some anonymous code, such as
EXEC moveSections.mergeUserSections('EMPTY_jbowerstest','A01','XC','G201','01.G1','G101','01.G1.G1');
