6 — Fetch contents of array

function, segment name, error status, array name, array

length

This function retrieves the named segment and stores the

contents in the named real, integer, or string array Integer Basic

only). The array must be specified by name. If the array length

value is specified, it must be a variable name. If it is

specified, RAMEXPAND will return the number of bytes actually

stored in the array in this variable. This can be used to deter-

mine how much data was returned. The number must be divided by

the size of an array element to determine how many elements it

represents. For integers, the size is 2 bytes. For reals, the

size is 6 bytes. For fetching Applesoft string arrays, use

function #16.

Error status:

0 = success

1 illegal function

2 = variable not found

8 = segment not found

9 = illegal segment name

11 = no array specified

7 — Exchange array

function, segment name, error status, array name, array

length

This function exchanges the contents of an array in normal

RAM with the contents of an array in extended RAM. Other than

the exchange, this function acts just like the Fetch Array

function. The array must be specified by name. If the array

length value is specified, it must be a variable name. If if is

specified, RAMEXPAND will return the actual number of bytes

stored in the array in this variable. This can be used to

determine how much data was returned. This number should be

divided by the number of bytes per array element to determine how

many elements it represents. For integers, the size is 2 bytes.

For reals, the size is 6 bytes.

Error status:

0 = success

1 = illegal function

2 = variable not found

8 = segment not found

9 = illegal segment name

11 = no array specified

1 2 ... 38 39 40 41 42 43 44 45 46 47 48 ... 76 77
