DEL
grifo^®
ITALIAN TECHNOLOGY
COMMAND:
DEL <line number>, <line number>
ACTION:
All program lines within the given interval are deleted from the current program. The second line
number must be strictly greater than the first.
EXAMPLES:
DEL 10,20
DEL 1000, 1075
REMARKS:
DEL is used to delete whole blocks of program lines at one time. If it is desired to remove only one
line, just type the appropriate line number, followed immediately by striking the <CR> key.
All variables are cleared as a result of DEL (or any other command which modifies the current
program).
Unless the deleted lines have been saved as part of a program on diskette, they will be permanently
lost and will have to be re-entered manually if needed later.
ERROR MESSAGES:
ARG ERROR
The second line number in the interval is not greater than the first.

One or both of the lines specified in the line number interval do not exist within the current program.
