where a tag number is used to identify a segment. Execution terminated.
Data on the NT, TL, EX, and PT cards should be checked.
2. CONNECT - SEGMENT CONNECTION ERROR FOR SEGMENT _.
Routine: CONNECT
Possible causes: number of segments at a junction exceeds limit;
segment lengths are zero; array overflow.
3. DATA FAULT ON LOADING CARD NO. =__ ITAG STEP1 =__ IS GREATER THAN

4. EOF ON UNIT __NBLKS = __NEOF = __.
Routine: BLCKIN, entry point of BLCKOT
An end of file has been encountered while reading data from the unit.

an error is indicated and execution will terminate.

A geometry data card was expected, but the card mnemonic is not that
of a geometry card. Execution terminated. After the GE card in a
data deck, the possible geometry mnemonics are GE, GM, GR, GS, GW,

XY plane. Execution terminated.
23. GEOMETRY DATA ERROR - - SEGMENT __ LIES IN PLANE OF SYMMETRY.
Routine: REFLC
A segment may not lie in or cross a plane of symmetry about which the
structure is reflected since the segment and its image will coincide or
cross. Execution terminated.
24. IMPROPER LOAD TYPE CHOSEN, REQUESTED TYPE IS __.
Routine: LOAD
Valid load types (LDTYP on the LD card) are from 0 through 5.
Execution terminated.
25. INCORRECT LABEL FOR A COMMENT CARD.
Routine: MAIN
The program expected a comment card, with mnemonic CM or CE, but
encountered a different mnemonic. Execution terminated. Comment cards
must be the first cards in a data set, and the comments must be
terminated by the CE mnemonic.
26. LOADING DATA CARD ERROR, NO SEGMENT HAS AN ITAG=__.
Routine: LOAD
ITAG specified on an LD card could not be found as a segment tag.
Execution terminated.
27. NO SEGMENT HAS AN ITAG OF __.

This error results from faulty input data and can occur at any point
where a tag number is used to identify a segment. Execution terminated.
Tag numbers on the NT, TL, EX, CP, PQ, and PT cards should be checked.
28. NOTE, SOME OF THE ABOVE SEGMENTS HAVE BEEN LOADED TWICE, IMPEDANCES
ADDED.

A segment or segments have been loaded by two or more LD cards. The
impedances of the loads have been added in series. This is only an
informative message. Execution continues.

35. PIVOT(__) = __.
Routine: FACTR (in-core) or LFACTR (out-of-core)
This will be printed during the Gauss Doolittle factoring of the
interaction matrix or the network matrix when a pivot element less than
10E-10 is encountered, and indicates that the matrix is nearly singular.
The number in parentheses shows on which pass through the matrix the
condition occurred. This is usually an abnormal condition although
execution will continue. It may result from coinciding segments or a
segment of zero length.

OPTION.
