The PRO statement defines an IDL procedure.
Examples
The following example demonstrates the use of arguments in a PRO statement:
PRO ADD, A, B
PRINT, 'A = ', A
PRINT, 'B = ', B
A = A + B
PRINT, 'A = ', A
END
PRO MYPROCEDURE
X = 5
; Call the ADD procedure:
ADD, 3, X
END
MYPROCEDURE
After you run myprocedure.pro, IDL returns:
A = 3
B = 5
A = 8
Syntax
PRO Procedure_Name, argument1, ..., argumentn
. . .
END
Arguments

A parameter that is passed to the procedure.
