Commands for
operating the index
register
The following commands are available for exchanging data between the word
accumulator and index register, or between the stack and index register:
 LX (Load index to accumulator)Index register – word accumulator
 =X (Store accumulator to index) Word accumulator – index register
 PSX (Push index register) Index register – stack
 PLX (Pull index register) Stack – index register
 INCX (Increment index register)
 DECX (Decrement index register)
Error and dialog
files
Starting with software version 05, indexed access to error and dialog files is
possible via the operands B/W/D.
In the example, a copy of S1 ("TEST" is loaded into S2, and S3 then contains
the string "TEST", but only starting from the 3rd character ("ST"). Also, indexed
access to error and dialog files is shown:
#define Ofs D100
#define Start D104
#define offset_dialog D108
#define offset_error D112
L S#"TEST"
=S1
LK1
= Ofs
LK2
= Start
=X
L S0[Ofs]
= S2
L S2^Start
=S3
LK5
= offset_dialog
L S#D10[offset_dialog]
= S0[offset_dialog]
LK6
= offset_error
L S#E10[offset_error]
= S0[offset_error]
