MERGE COMMAND
The MERGE command allows you to merge all or part of a saved type file with data
or a program (saved in BASIC format) in the work area. In this way. you can add
the same routine to several different programs. or add the same data items to several
different data files. Only BASIC statements (in a BASIC file) and DATA files car
be merged. The work area and saved file must be of the same type. If these files are
different, the MERGE command is not executed, and an error message is displayed.
Lines from the tape file are added to the work area lines in line number sequence.
If a line from the tape file and a line in the work area have the same statement
number, however. the line from the file replaces the work area line. The merged
file could exceed the size of the work area. which causes an error message to be
displayed (see Appendix B).
As the lines are merged, you can specify that lines merged from the file be renumbered.
starting with a statement number of your choice and increasing by the original file
increment. After the merge is completed, the display shows the READY message.
along with the number of unused bytes in the work area. The syntax of the MERGE
command is as shown:
MERGE file-num
G
[from line-numl. [through line-numl. [new line-numl [,dev-addressl]
where:
file-num is the number of the saved file to be merged.
from line-num is the first line to be merged in the saved file. If no number is
entered, the first line in the file is the default.
through line-num is the last line to be merged in the saved file. If no number is
entered, the last line in the file is the default.
new line-num is the first line number to be used in renumbering the lines from the
saved file. If no number is entered. the merged file will not be renumbered.
de v-address is the address of the tape unit in which the saved file resides. The
default is the built-in tape unit (E80).
