STR$
STR$ returns the string representation of its argument.
CONFIGURAITON
a$ = STR$(a)
In the following example , A$ would consist of the string "40". In
this case, "40" is a string--not a number . In other words, "40" (in
its string
equivalent) would not be used in ca lcu lations.
TRAP
EXAMPLE
050 DIM A$(50)
150 A$ = STR$(40)
200 PRINT A$
RUN
40
The TRAP statement causes program execution to branch to the
line number indicated when an error is encountered.
CONFIGURA TlON
TRAP LN
TRAP must have been executed prior to the occurrence of the
error. Otherwise , a branch to the indicated program line will not
take place.
TRAP
will invalidate the Atari's automatic error handling routine
which halts program execution.
