How to Access Built-in Windows
To let the user select a file, use the Pick File command.
path = Pick File(
, ,
, , ),
The prompt message is used as the window title. The "initial directory" defines which folder initially
appears. If a directory is defined as an empty string, the default directory is used.
You can also define the filter used for the Open window, forcing it to show only certain file types. This list
must use the following syntax:
{"Label1|suffix1;suffix2;suffix3", "Label2|suffix4;suffix5"}
Each quoted string adds an entry to the File name list in the Open window. Label defines the text that is
displayed for each menu option. The following list of suffixes defines the file types that are displayed if its
corresponding label is selected. Note the use of * to list all files in the window.
Pick File(
"Select JMP File",
"$SAMPLE_DATA",
{"JMP Files|jmp;jsl;jrn",
"All Files|*"},
1, 0, "Earthquakes.jmp")
Tip: All arguments are optional, however, they are also positional. This means that you can leave out
arguments only at the end of the script. Use empty strings for the arguments that you want to omit from the
beginning of the script.
To obtain a list of filenames in a specific directory, use the Files In Directory command.
names = Files In Directory(path, );
On Macintosh, only the filenames are returned. On Windows, both filenames and subdirectory names are
returned as shown in the following example:
names = Files In Directory("$SAMPLE_DATA");
{ "2D Gaussian Process Example.jmp", "Abrasion.jmp", ... "Design
Experiment", "Detergent.jmp", ... }
Notice that the files within the Design Experiment subdirectory are not included. And only files in the
root $SAMPLE_DATA directory are listed. To return a list of all file names, add the optional recursive
argument to Files In Directory:
names = Files In Directory("$SAMPLE_DATA", recursive);
{ "2D Gaussian Process Example.jmp", "Abrasion.jmp", ... "Design Experiment/
2x3x4 Factorial.jmp", "Design Experiment/Borehole Factors.jmp", ... }
To get the full pathnames, recurse the directories and concatenate the file paths and file names. The
following example loops through each file in the $SAMPLE_DATA directory and subdirectories. The file path
is concatenated to each file name.
