THE ADVANCE STATEMENT CAUSES THE SPECIFIED FILE (SIGNIFIED BY THE
|
||
FILE NUMBER) POINTER TO BE MOVED PAST THE NUMBER OF ITEMS
|
||
SPECIFIED IN THE SKIP COUNT. THE SKIP COUNT IS LIMITED TO 32767 AND
|
||
MUST BE A POSITIVE INTEGER. IF THE 'ADVANCE STATEMENT IS EXECUTED SUCCESSFULLY
|
||
THE RETURN VARIABLE IS SET TO '0'. IF AN END-OF-FILE MARKER IS ENCOUNTERED
|
||
BEFORE THE SPECIFIED NUMBER OF ITEMS HAVE BEEN SKIPPED THE RETURN VARIABLE
|
||
WILL BE SET TO THE NUMBER OF ITEMS YET TO BE SKIPPED. THE ADVANCE
|
||
STATEMENT CANNOT BE USED WITH ASCII FILES.

|
||
|
||
THE ASSIGN STATEMENT IS USED TO ASSIGN A FILE TO A FILE NUMBER
|
||
RESERVED IN THE FILES STATEMENT (eg. 100 FILES *,*,*) AND TO OPEN THE
|
||
FILE. THE FILE DESIGNATOR CAN BE A STRING OR CAN BE ENCLOSED IN QUOTES
|
||
BUT IT MUST BE A VALID FILE NAME. IF AN ASTERISK (*) IS USED IN PLACE
|
||
OF THE FILE DESIGNATOR THE FILE PREVIOSLY ASSIGNED TO THAT FILE
|
||
NUMBER IS CLOSED. THE OPTIONAL MASK IS A STRING USED TO SCRAMBLE BASIC
|
||
FORMATTED FILES AS TO MAKE THEM 'GREEK' TO USERS NOT ACCESSING THE FILE
|
||
WITH THE SPECIFIED MASK. THE SAME MASK MUST BE USED
|
||
WHEN READING FROM THE FILE AS WAS USED WHEN IT WAS PRINTED ON THE FILE.
|
||
THE OPTIONAL RESTRICTION IS A TWO-LETTER CODE USED TO SPECIFY ACCESSABILITY
|
||
RESTRICTIONS ON THE FILE. RESTRICTION CODES ARE AS FOLLOWS:
|
||
|
||
|
||
RR NO SUBSEQUENT USER CAN ACCESS THE FILE WHILE
|
||
THE FILE IS OPEN
|
||
|
||
WR SUBSEQUENT USERS CAN READ FROM BUT CANNOT WRITE
|
||
TO WHILE THE FILE IS OPEN
|
||
|
||
NR SUBSEQUENT USERS CAN READ & WRITE WHILE THE FILE IS
|

ACCESS FOR THIS RESTRICTION).

THE CHAIN STATEMENT CAUSES THE CURRENT RUNNING PROGRAM TO TERMINATE
|
||
AND BEGIN EXECUTION OF THE PROGRAM SPECIFIED BY THE PROGRAM DESIGNATOR.
|
||
THE PROGRAM DESIGNATOR MAY BE ENCLOSED IN QUOTES OR MAY BE A STRING.
|
||
THE NUMERIC EXPRESSION CAN BE USED TO DEFINE A LINE NUMBER IN
|
||
THE PROGRAM TO BE CHAINED TO. IF SUCH AN EXPRESSION IS DEFINED PROGRAM
|
||
EXECUTION WILL BEGIN AT THE SPECIFIED LINE NUMBER.

GEN. FORM: DEF FUNCTION NAME(PARAMETER)=NUMERIC EXPRESSION
|
||
|
||
|
||
THE 'DEF' STATEMENT IS USED TO DEFINE A FUNCTION
|
||
SUCH AS: A**2/(SQR(X)). HERE IS AN EXAMPLE OF A USER DEFINED FUNCTION:
|
||
|
||
10 DEF FNA(X) = A**2/(SQR(X))
|
||
|
||
ALL FUNCTION NAMES MUST BEGIN WITH 'FN' AND HAVE A THIRD CHARACTER
|
||
BETWEEN 'A' AND 'Z'. THE 'X' IN PARENTHASIS IS A DUMMY VARIABLE.
|
||
ITS PURPOSE IS TO SHOW WHAT ARGUMENT WILL BE USED WHEN THE FUNCTION
|
||
IS SUMMONED.

THE DIM STATEMENT IS USED TO SET THE AMOUNT OF SPACE ALLOTED
|

PROGRAM. IT MAY OCCUR ANY WHERE IN THE PROGRAM BUT THE END STATEMENT
|
||
MUST ALWAYS OCCUR AT THE END OF A PROGRAM.

GEN. FORM: FILES FILES LIST
|
||
|
||

THE GOSUB STATEMENT IS A WAY OF DROPPING TO ANOTHER PART
|

OF THE PROGRAM BUT STILL KEEPING YOUR PLACE WHERE YOU ARE SO
|
||
YOU CAN RETURN AND CONTINUE ON WITH THE PROGRAM. IF GOSUBS ARE
|
||
NESTED MORE THAN 20 DEEP THEN THE PROGRAM WILL TERMINATE WITH

THE GOTO STATEMENT OVERRIDES THE NORMAL ORDER THAT STATEMENTS
|
||
ARE CARRIED OUT. IT TELLS THE PROGRAM TO SKIP TO THE SPECIFIED LINE
|
