Arrays and functions of long integers?
Arrays and functions of long integers?
(OP)
Two questions:
1) How do I create arrays of long integers?
This statement creates an array of short (two byte) integers. But what is the comparable statement for an array of long (four byte) integers?
2) How do I create a function that returns a long integer?
This code returns a short integer. But what is the comparable code for a function that returns a long integer?
1) How do I create arrays of long integers?
CODE
DIM A(100) AS INTEGER
This statement creates an array of short (two byte) integers. But what is the comparable statement for an array of long (four byte) integers?
2) How do I create a function that returns a long integer?
CODE
DECLARE FUNCTION name% ()
PRINT name%
FUNCTION name%
result% = 10 ' an integer under 32767
name% = result%
END FUNCTION
PRINT name%
FUNCTION name%
result% = 10 ' an integer under 32767
name% = result%
END FUNCTION
This code returns a short integer. But what is the comparable code for a function that returns a long integer?

1.
DIM myArray() AS LONG
2.
FUNCTION func
myLong& = 2147483647
func& = myLong&
END FUNCTION

RE: Arrays and functions of long integers?
BTW I'm using the Microsoft user's manual which is, frankly, crap. It's not answering any of my questions. In this case there was nothing about LONG or using the & suffix. They just gave us DEFLNG and some sales-type talk about how wonderful and convenient long integers are.
Can you recommend a manual that has a comprehensive alphabetical list of all the commands and statements?
Note that I am not a total beginner. I don't need a Dummies-type book that spends 50 pages describing FOR/NEXT loops. I just need something more comprehensive than that half-baked manual that Microsoft published 20 years ago.

It was the first one listed for me. I don't know if it has everything you're looking for but you can compare their list to the F1 in QB.
HTH.

Example:
DIM MYVALUE&(100)
CREATES A TABLE OF LONG INTEGERS OF +- 2 BILLION
DIM A#(100)
CREATES A TABLE OF LONG FLOATING POINT OF 8 BYTES WITH 15 DIGITS WHICH IS AS BIG AS IT GETS
-----------------------------------------------------------
THE FOLLOWING ARE DATA DEFINITION AND TRANSFORMATION STATEMENT EXAMPLES:
A$ = "STRING" :' CREATES A STRING OF CHARACTERS UP TO 32,767 BYTES LONG
A% = 6 :' CREATES A SHORT INTEGER UP TO +32K = 2 BYTES BINARY + SIGN
A& = 1456789 :' CREATES A LONG INTEGER UP TO +2 BILLION = 4 BYTES BINARY + SIGN
A! = 123.456 :' CREATES A SHORT +FLOATING POINT NUMBER = 4 BYTES WITH 7 DIGITS x1038
A# = 1234567.123 :' CREATES A LONG +FLOATING POINT NUMBER = 8 BYTES WITH 15 DIGITS x10308
A% = X\Y :' RETURNS THE INTEGER VALUE OF THE DIVIDE
A% = X MOD Y :' RETURNS THE REMAINDER AFTER DIVIDING X BY Y
A% = INT(3.685) :' RETURNS "3" THE ROUNDED DOWN VALUE OF "3.685)
A% = FIX(3.685) :' RETURNS "3" THE TRUNCATED VALUE OF "3.685)
A% = CINT(3.685) :' RETURNS "4" THE ROUNDED UP VALUE OF "3.685"
A& = CLNG(3.685) :' RETURNS A LONG INTEGER VALUE "4" THE ROUNDED UP VALUE OF "3.685"
A@ = 23.67 :' CREATES A CURRENCY VALUE
DIM MYVALUES(50) :' A REAL NUMERIC TABLE WITH 50 ENTRIES
DIM NAMELIST$(200) :' A CHARACTER TYPE TABLE WITH 200 ENTRIES
DIM BOWLINGSCORES(60,100) :' A TWO DIMENSIONED TABLE WITH 60 ENTRIES OF A 100 ENTRIES EACH
