Conventions and Data Display
Interrupt Sequence
Commands that operate on many lines or are executed a multiple of times (global modify, page modify, locate, block move, etc.) may be terminated in one of two ways. All commands that perform more than a single task or operation (except the ':FD' and ':FL' commands) may be terminated by one of two ways. The first is with use of the ESCAPE key. This immediately aborts any repetitive command currently being executed. The second is by typing the standard operating system interrupt sequence. At this time, the command terminates execution and positions the cursor for entry of another command.
Record Display
If used for the creation and modification of program source files, almost all lines are less than 79 bytes long. However, if it is being used to modify actual data files, these records may exceed 79 bytes and are displayed on the screen as multiple lines. During the actual edit procedure, these are treated as separate lines. During the input and output sections, they are concatenated to form one logical record. Records longer than 79 bytes are indicated by a tilde '~' in the last position of the line being continued.
To create a record longer than 79 bytes, enter the tilde as the last character on one line and continue the data on the following line. During the output section, that line is combined with the following line(s).
Trailing Spaces
When used for the modification of data files, it is extremely important that any records with trailing spaces be rewritten with a user program after the edit is completed (if these trailing spaces are actually needed). During the edit procedure, any trailing spaces are removed since they are not necessary for source files and their removal saves space on the disk.
Conventions
Throughout this help file, reference is made to command characters, to tab characters, and to examples of each. If these characters have been modified, the new character may be substituted in place of those shown. The default characters are used throughout for explanatory purposes and are the characters in effect upon execution of the editor.
