FileType macro command

Print this Topic Previous pageReturn to chapter overviewNext page

Macro commands may be used either in macros or by sending the commands to DPlot via dynamic data exchange (DDE). Some commands are valid only in macros (noted by Macros Only). Commands sent to DPlot via DDE must be enclosed by square brackets [     ]. Macro commands should not include the brackets.

Command parameters shown in the descriptions below are placeholders for the actual values. Command parameters are either numeric values, equations that evaluate to numbers, or character strings. Character string parameters are always bound by double quotation marks. Equations must be preceded by an equals sign (=).

The pipe symbol (|) in the command syntax indicates that a parameter is optional, and should not be included in your macro unless otherwise noted.

All indices into arrays are 1-based, e.g. Curve1=1 refers to the first curve in a plot.

A 0x prefix for numbers in the descriptions below indicates hexadecimal notation; e.g. 0x0010 = 16.

JR/Viewer indicates that the command is supported by DPlot Jr or DPlot Viewer.
JR/Viewer indicates that the command is NOT supported by DPlot Jr or DPlot Viewer.


[FileType("Plugin Description")

JR   Viewer

Sets the file type code prior to opening a document with the FileOpen command. n is one of:



DPlot file



ASCII file, one data set with arbitrarily spaced points.



ASCII file, one data set with evenly spaced points.



ASCII file, multiple columns.



Unformatted data, 32-bit floating point values.



Binary file produced by Pacific Data Model 9820 recorders, DNA/Bendix format.



Binary file produced by Pacific Data recorders, OLD format.



Binary file produced by Pacific Data recorders, NEW format.



Nicolet Time Domain files (binary) created with the Nicolet System 400 Digital Oscilloscope.



Hardened Data Acquisition System (HDAS) files.



3 columns of randomly-spaced 3D points (X,Y,Z)



1D amplitudes (opened as a Box and Whisker plot by default)



ASCII text file, tab-separated columns



Compressed DPlot file



Unformatted data, 64-bit floating point values.



Identical to 11, but interpreted as a 3D scatter plot rather than a surface plot.

For more information on file types, see the description of the Open menu command.. If the "Plugin Description" form is used, the descriptive string must exactly match the description shown in the Select File Type dialog box, e.g. "WAV Audio".


Please note:

Character string arguments require a bit of care, depending on your development environment. Character string arguments in all DPlot commands are always enclosed by double quotation marks. In some environments (Visual Basic and all flavors of C, for example), double quotation marks are also used to delineate all character strings (including the command itself). The following example will always cause a syntax error in Visual Basic:

ret = DPlot_Command(docnum,"[FileOpen("myfile.grf")]")

Instead, use:

ret = DPlot_Command(docnum,"[FileOpen(""myfile.grf"")]")

in C, C++, C# you'd accomplish the same thing with:

ret = DPlot_Command(docnum,"[FileOpen(\"myfile.grf\")]");

If a character string argument is a variable, as in (VB):

Dim arg as string
arg = "myfile.grf"

... then you can build the command in VB as:

ret = DPlot_Command(docnum,"[FileOpen(" & chr$(34) & arg & chr$(34) & ")]")

In all flavors of C, the same can be accomplished with

char arg[256];
char cmd[512];
ret = DPlot_Command(docnum,cmd);

This does not apply to the DPlot macro editor, in which each line is by definition a character string and does not require delineators, nor to FORTRAN and possibly other languages, in which the delineator for character strings is a single quote, e.g. '[FileOpen("...")]'

To embed a double quotation mark within a character string which is itself delineated by double quotation marks, use the Symbol font equivalent instead. For example, "Radius=6{\s²}" inches will be processed as
