TAB file with no Updates

If TABLO successfully generates code (for either GEMSIM or FORTRAN) from a TAB file containing equations and variables, the LOG and INF files should contain (near the end) lines like:

This program

o can create the Equations file

o can carry out multi-step simulations

or maybe

When used with GEMSIM, the GEMSIM Statement

and Table files produced in this run of TABLO

o can create the Equations file

o can carry out multi-step simulations

Occasionally the line:

o can carry out multi-step simulations

is missing (but TABLO gives no error or warning). In this case, if you run the model no solution file will be created.

Almost certainly the reason is that your TAB file contains no update statements.

TABLO expects that every valid model contains update statements: if these are missing the code to run simulations is not generated.

To avoid the problem, include at least one update statement in the TAB file (if that TAB file contains equations and variables). For example, include a line like:

Coefficient Z; Formula(initial) Z=0; Update(change) Z=0;

Since April 2010, TABmate will warn you about this problem if you used one of the TABLO Code or TABLO STI buttons to generate code.
