Some FHWA TNM users had experienced floating point errors for certain case runs in Version 1.0. FHWA TNM Version 1.0a corrected these errors for the most common floating point error bug. The FHWA TNM Version 1.0a is an update to the FHWA TNM Version 1.0 release package. It requires the complete release package for use.
To use Version 1.0a, download TNM1_0A.EXE, rename it to TNM.EXE, and then replace the existing TNM.EXE file located in your TNM/PROGRAM directory with the new executable file.
The previous version of NMPlot was having difficulties running on very fast computers (typically faster than 200 MHz) giving some users a runtime error message. The developer of NMPlot has recently released a new DOS version of NMPLOT, Version 3.06, which corrects this error. To use Version 3.06, replace the existing NMPLOTX.EXE file located in your TNM/PROGRAM/NMPLOT directory with the new executable file.
