Example of
Module 9010
January 2012
Module 9010/9011/9012 Read in the word range
From the specified location in the word memory the control reads a byte, word
or double word and returns it as an output quantity to the stack. Indexed
reading is possible by specifying a variable as designation of the memory
location.
Call:
PS B/W/D/K <Address of the byte to be read>
CM 9010 ; READ BYTE
PL B <Target address for byte that was read>
PS B/W/D/K <Address of the word to be read>
CM 9011 ; READ WORD
PL B <Target address for word that was read>
PS B/W/D/K <Address of the double word to be read>
CM 9012 ; READ DOUBLE WORD
PL B <Target address for double word that was read>

Initial state:
Byte B10 = 35 (address)
Byte B35 = 80 (byte to be read)
Byte B100 = ?
