If you have a variable you transferred from the HP 48 to your PC
using Kermit, you can easily load it into the HP 48 Program
Development Link (PDL) environment. Here's how:
1. Start PDL.
2. Execute File / Open Application. Type the name of the file
containing the variable (e.g., "FRED.VAR") and choose OK.
PDL interprets the "%%HP" header line (if any) in the variable
file and sets the proper modes for your new application. The
variable is initially unnamed.
3. Execute Variable / Name/Move Variable. Type the name of the
variable (e.g., "FRED") and choose OK.
You've now created a new PDL application consisting of the
variable loaded in step 2. To simplify future work with the
application, you should save it in a file with the ".APP"
(application) file name extension. (Remember that PDL
distinguishes between HP 48 variable names [which are highly
flexible in format] and DOS file names [which must match rigid
DOS file naming conventions].)
4. Execute File / Save As. Replace the old extension (if any)
(e.g., ".VAR") with ".APP" and choose OK.
The variable (and your new application) can now be maintained with
PDL. You can edit the variable, add new variables to the
application, transfer the variable(s) to the HP 48, and so on.
This technique works for an ASCII-format variable obtained from most
any source, including your own editor. For HP 48 directory
variables, you should use a text editor to divide the directory
contents into individual variables first. See "Converting
Applications from Other Formats" in "Creating and Editing
Applications" in the PDL on-line Help.
