Conversion of numbers from the stack calculator
a character string.
With a built-in calculator, the results are on top of the
stack kalkulyatornogo in integral form. To print them a routine
Print_FP.No it prints the standard tools, which are now rarely
used. Typically, the program works with own procedures for
printing, for example, 42 characters per line. It can be
attributed to a new flow. But it must be pretty close
communication with the operating system Spekki.Predpochtitelney
simply convert that number into a string of characters and
dispose of it at their discretion. But program for such a
transformation will rather complicated and cumbersome. Simply
take advantage of the ROM.
The first thing that comes to mind - Print_
FP. It prints the number from the top of the stack
calculator in the current thread. Means to
substitute procedure for deriving the symbol of the procedure
sending bytes in memory. But far too cumbersome. However
Print_FP with their work creates a symbolic representation
numbers, and only then calls the routine. The buffer is in the
workspace calculator at # 5CA1-# 5CAA.Eto two
memory calculator MEM3 and MEM4.
Now, simply as an Inference Procedure for the flow of supply
and RET cause Print_FP, to consider a string
representation of numbers. This is easier, though
still need to fiddle with the channels. Simply
only use for this function
calculator STR $. Converter takes 7
bytes.
CONVERT RST # 28; call calculator
DB # 2E, # 38; Teams calculator:
; STR $ converts the number in the
string.
, Now on the stack the parameters of
this
; Thong. In DE-address, in BC-length.
; END_CALC - output from the
calculator.
CALL # 2BF1; Sub-STK-FETCH rewritten
; Vaeth number from the stack
calculator
; In registers A, B, C, D, E. And
since
; After surgery STR $ stack we find
; Converge options thong, then they
, Transferred to a pair of DE and BC.
RET
That's it. It remains to copy the string
in a more secure place than the workspace
interpreter.
