MERGE
Field of Application Statement for merging a program in the printer’s current directory, or
optionally in another specifi ed directory, with the program currently
residing in the printer’s working memory.
Syntax MERGE<scon>
<scon> is the name (optionally including a reference to another
directory than the current one) of the program, which is
to be merged with the program currently residing in the
printer’s working memory.
Remarks
MERGE creates a copy of a program stored in the current directory
(see CHDIR statement), or optionally in a specifi ed other directory,
and blends its lines into the program currently residing in the printer’s
working memory.
Important:
If there are lines with the same numbers in both programs, the lines in the
program currently residing in the working memory will be replaced by the
corresponding lines in the MERGEd program. This also applies to programs
written without line numbers, since they will automatically be assigned
hidden line numbers (10-20-30... etc.) at the execution of the IMMEDIATE
ON statement. In order to avoid overwriting any lines, you may SAVE a
program without line numbers using a SAVE <scon>, L statement. When
MERGEd, it will be appended to the current program and assigned line
numbers that start with the number of the last line of the current program plus
10. For safety reasons, a backup copy of the current program is recommended
before issuing a MERGE statement.
MERGE makes it possible to store blocks of program instructions, which
are frequently used, and include them into new programs. The printer’s
ROM memory contains a number of useful programs, which also can be
MERGEd into programs of your own creation.
Be careful not to include any MERGE statement as a part of a program,
or else the execution will stop after the MERGE statement has been
executed.
The EXECUTE statement offers an alternative method for combining
Fingerprint programs.
Examples The program “XYZ.PRG" will be merged with the current program. If there
are identical line numbers in both programs, the lines from “XYZ.PRG"will
replace those in the current program.
MERGE "XYZ.PRG" (from current directory)
MERGE "c:XYZ.PRG" (from permanent memory)
MERGE "tmp:XYZ.PRG" (from temporary memory)
MERGE "rom:XYZ.PRG" (from read-only memory card)
MERGE "card1:XYZ.PRG" (from DOS-formatted memory card)
