- * CSAVE!
- Causes TARBELL BASIC to write itself and optionally, system monitor
- onto cassette tape. This is handy for making patches.
- Example: CSAVE!
-
- * DELETE <line descriptor> [<line descriptor>]
- Eliminates the line(s) indicated from the stored program. If only
- the first <line descriptor> is present, only that one line is deleted.
- If both <line descriptor>'s are present, both those lines, and
- all lines in between are deleted. If there is no such line
- descriptor, an error message is issued.
- Examples: DELETE START+4 DELETE LOOP LOOP+5
-
- * ENTER [<line descriptor>] or :[<line descriptor>]
- Causes TARBELL BASIC to go to program entry mode. Any input after
- this statement is interpreted as program statements. A carriage
- return delimits each line. The "ENTER" statement is provided to
- allow statements without names to be entered. If <line descriptor>
- is ommitted, entry begins after the last statement currently in
- memory. If <line descriptor> is present, entry begins immediately before
- the line indicated. Entry mode is terminated by two carriage returns
- in a row. Multiple statements per line are allowed if separated by a colon.
- The colon shown in the command format above, however, is a shorthand
- form of ENTER, the same way that "?" is a shorthand form of PRINT.
- The first line in a program should always have a label.
- If any of the following commands are invoked from entry mode, they
- will be performed, then command mode will be reentered:
- LIST,DELETE,EDIT,RUN.
- Examples: ENTER ENTER ADDC+3 ENTER LOOP : START+1
-
- LIST [<line descriptor>] [<line descriptor>]
- Lists the program starting from the statement corresponding with
- the first <line descriptor>, until the end is reached, if there is no
- second <line descriptor>, or until a control/C is entered.
- If neither <line descriptor> is present, the whole program is listed.
- Examples: LIST LIST START+10 LIST LOOP END1
-
- NEW
- Deletes the program in memory, clears all variables, releases all
- string and array space. Example: NEW
-
- RUN [<line descriptor>]
- If the line descriptor is included, starts execution of the BASIC
- program at the line specified. If the line descriptor is ommitted,
- execution begins at the first line in memory. In either case, a
- CLEAR is automatically executed first.
- Examples: RUN RUN COMD RUN SUBROUTINE+1
-
- * SYMBOL
- Types a table of variable names, line descriptors, their types and
- their locations. Example: SYMBOL
