Tandem Capacity Model (TCM) Manual

3. Select History > Chart History.
• If the History file contains data for more than one apportionment method, TCM prompts
you to select the desired apportionment method to use when creating the History charts.
• If TrendCharts sheets, MixCharts sheets, or both are already part of the History file, the
History Chart Overwrite Warning dialog box appears. To create new Trend charts and
Mix charts (the existing ones are deleted automatically), click both checkboxes. This
approach is recommended. Clearing either check box causes TCM to not overwrite that
Chart sheet. When you are finished making your selections, click OK.
4. When the History Charts dialog box appears, select the desired chart size: 1/4 screen, 1/2
screen (horizontal), 1/2 screen (vertical), 2/3 screen (the default), or Full screen. Then click
OK.
TCM creates the requested History charts in the specified size. Progress messages appear in
Excel's status bar at the bottom of the screen while the History charts are being created.
Customizing the MeasTCM CNTLFILE
When you have completed the process flow diagram, you must translate it into process category
(PCAT) statements for MeasTCM. A template of the control file (CNTLFILE) is available in the
MeasTCM installation subvolume (ZMEASTCM). To define the process categories for your Measure
data, copy the template control file to your working subvolume and edit the file according to your
application needs. For detailed information about the CNTLFILE and its sections, see “Customizing
Your Process Category Control File” (page 33).
Customizing Help Messages
If you have a help compiler, you can change the text of any help message to customize it. The text
for TCM help messages is contained in three files: tcmtxt.hwa for the WA model, tcmhpm.txt for
the Performance model, and tcmtxt.hxp for TCM Expert. The Helpconv utility or equivalent help
compiler must be obtained from Microsoft.
To customize help messages:
1. Use any text editor installed on your workstation to open the help file (tcmtxt.hwa, tcmhpm.txt,
or tcmtxt.hxp).
2. Locate the name of the field with the help message you want to change by scrolling through
the file. The names of all fields are preceded by asterisks (*).
3. Edit the text and save the file.
4. Convert the revised file to a format understandable to Microsoft Windows.
