111 SHARED
Enables sub-procedure referencing without passing on the variable
Format
SHARED variable(), variable()...
Explanation This statement allows variables declared with a program level code to be referenced
with a sub-procedure without passing on the variables as dummy arguments.
The program level variable used by the sub-procedure is specified by the < variable >
value.
A simple variable or an array variable followed by parentheses is specified. If an array
is specified, that entire array is selected.
• Normally, a dummy argument passes along the variable to a sub-procedure, but the SHARED
statement allows referencing to occur without passing along the dummy argument.
• The SHARED statement allows variables to be shared only between a program level code and
sub-procedure which are within the same program level.
SAMPLE
DIM Y!(10)
X!=2. 5
Y!(10)=1. 2
CALL *DISTANCE
CALL *AREA
HALT
SUB *DISTANCE
SHARED X!,Y!( ) ·············· Variable referencing is declared by
SHARED.
PRINT X!^2+Y!(10)^2 ·········· The variable is shared.
END SUB
SUB *AREA
DIM Y!(10)
PRINT X!*Y!(10) ·············· The variable is not shared.
END SUB
Related commands SUB, END SUB
NOTE
• The program level code is
a program written outside
the sub-procedure.
