The user may select the continue option in order to load more program modules,
possibly to satisfy undefmed references.
If
continue is selected the "LOAD/END"
question will be asked again.
3.4.6.3 Error Messages. PX9LAL prints an error message when it detects an error. One message
is for a command processor error. There are four fatal errors that terminate execution of
PX9LAL following the printing of the error message. There are four other error messages that
serve as warnings. PX9LAL continues the load operation following the printing of these
messages.
Command Processor Error. This message is:
**MX03** PX9LAL Not Loaded in Transient Area
PX9MTR prints this message when it determines that PX9LAL
is
not resident in the monitor
transient area. Load the overlay and reenter the command.
Fatal Errors.
The first inessage is:
**LLOI ** Illegal Load Sequence
In a module, PX9LAL will accept no other field except a field having a tag character of D ahead
of a field that is preceded by a tag character of O. PX9LAL will not accept a field preceded by
tag character D after it has read a field preceded by the tag character O. When PX9LAL reads a
field . of the object code out of sequence, it prints this message. PX9LAL then terminates and
restarts. The user may recover from the error by correcting the sequence of the object code and
reloading the program.
The second message is:
**LL02** Invalid Load Code
PX9LAL prints this message when it reads an invalid character as the tag character. Valid tag
characters processed by PX9LAL are the hexadecimal digits 0 through D and P, G,and H. Tag
characters G and H are symbol table tags in the 990/10 Disc System Software, but PX9LAL
ignores them.
When this error occurs, the PX9LAL module (but not the entire link sequence) terminates and
restarts. The user may recover from the error by correcting the object code and reloading· the
program. The error in the object code may be an error in entering the tag character. It may also
be a legitimate tag character used incorrectly, causing PX9LAL to consider a character in a label
or a character string as a tag character.
The third message is:
**LL03**
Missing End Statement
PX9LAL prints this message when a second tag character 0
is
followed by a nonblank IDT
character string in the same object module (no end-of-module record between the two). An
object module may contain more than one field with a tag c.haracter of 0, but the IDT character
string associated with a subsequent 0 tag must be blank.
