The address of this routine is found in the parameter table.
During syntax checking a DATA statement is checked to ensure that it contains a series of valid expressions, separated by commas. But in 'run-time' the statement is passed by.
|
||||
| DATA | 1E27 | CALL SYNTAX_Z | Jump forward unless checking syntax. | |
| 1E2A | JR NZ,DATA_2 | |||
|
A loop is now entered to deal with each expression in the DATA statement.
|
||||
| DATA_1 | 1E2C | CALL SCANNING | Scan the next expression. | |
| 1E2F | CP "," | Check for a comma separator. | ||
| 1E31 | CALL NZ,CHECK_END | Move on to the next statement if not matched. | ||
| 1E34 | RST $20 | Whilst there are still expressions to be checked go around the loop. | ||
| 1E35 | JR DATA_1 | |||
|
The DATA statement has to be passed by in 'run-time'.
|
||||
| DATA_2 | 1E37 | LD A,$E4 | It is a 'DATA' statement that is to be passed by. | |
|
This routine continues into PASS_BY.
