int e l 4.3 DESCRIPTION OF STATEMENTS STATEMENT: CLEAR MODE: COMMAND AND/OR RUN TYPE: CONTROL The CLEAR STATEMENT sets all variables equal to 0 and resets all BASIC evoked interrupts and stacks. This means that after the CLEAR statement is executed an ONEX1 or ONTIME statement must be executed before MCS BASIC-52 will acknowledge interrupts. ERROR trapping via the ONERR statement will also not occur until an ONERR[integer] STATEMENT is executed. The CLEAR STATEMENT does not affect the real time clock that is enabled by the CLOCK1 STATEMENT.
CLEAR also does not reset the memory that has been allocated for STRINGS, so it is NOT necessary to enter the STRING [expr], [expr] STATEMENT to re-allocate memory for strings after the CLEAR STATEMENT is executed. In general, CLEAR is simply used to "erase" all variables. VARIATIONS: None. - 30 -
