Writing Strings to DAT

coryco2

Is is possible to write more than one byte of data at a time in a DAT data block? I know I can do this:

PUB  MemTest
  byte[@myStr]:="T"

DAT
  myStr  byte  " ", 0

to write "T" to the data item myStr, so is there any simple way to write more than a single byte to the data item at a time, such as

byte[@myStr]:="Test String"

to store "Test String" in the myStr data item?

You can initialize myStr to "Test String" as follows:

DAT
  myStr byte "Test String", 0

Or if you want to copy the string to myStr at run time you can do

PUB MemTest
  bytemove(@myStr, string("Test String"),  12)
DAT
  myStr byte 0[12]

or you could use myStr as a pointer.

PUB MemTest
  myStr := string("Test String")
DAT
  myStr long 0

Ah! Figured it out:

bytemove( @myStr, string("Test"), 4)

Dave Hein

In your example you need to copy 5 bytes to get the terminating NULL byte.
