Manipulating Files 5-5
Programs are entered onto the User menu in a similar manner as the previous User
menu, except that there are memory and directory issues to clarify.
Name Selection
When you enter a program into the User menu, you must create a descriptive name
for the program, under which the program will be listed in the User menu. The
actual filename for the file does not change.
To create a descriptive name for the file:
1. Select the
Create<Ins>
option from the User menu.
2. Enter a descriptive name, up to 120 characters, as you would like it to appear
on the User menu.
Selecting a Filename
For the user-defined program feature to work correctly, you must enter the actual
filename of the program as it appears in you personal computer’s directory.
Typically, you have to enter more than just the filename here. Unless the file resides
in the current working directory, you have to provide a complete DOS path for the
program.
To select the actual filename:
1. Highlight the select a Filename option and press
[Enter]
or click the left
mouse button.
A dialog box appears, giving you the option to view a directory listing of you
personal computer. Use this directory listing to move through your directories
and disk drives until you find the actual name that you want to enter into the
User menu.
2. Highlight the program that you want and press
[Enter]
or select it with the
mouse.
The filename, along with its complete DOS path, is entered for the selected
program.
After selecting the actual filename, move down to the Swap method option.
Swap Method Selection
The
Swap method
option in this dialog box refers to how memory is allocated
when executing a user-defined program while still retaining the active files and
current screens being used in the BASIC Development Software.
The following table contains a brief explanation of the options available under the
Swap method option.
