Passaggio di variabili e funzionalità a una macro

When a Macro is created, it can receive from the DMIS program both Variables and Features as argument.

Passing Variable to A Macro

In order to pass a variable to a Macro it is necessary to define in the macro declaration that the argument is a variable:

$$ Example of a MACRO Used with Variable
M(PASSING_A_VARIABLE)=MACRO/MYVARIABLE


DECL/LOCAL,CHAR,128,tmpString


tmpString=ASSIGN/CONCAT('The Variable Passed is: ',STR(MYVARIABLE))


TEXT/OPER,tmpString


ENDMAC

DECL/DOUBLE,PASSED_TO_MACRO
PASSED_TO_MACRO=ASSIGN/100

CALL/M(PASSING_A_VARIABLE),100
CALL/M(PASSING_A_VARIABLE),PASSED_TO_MACRO


Passing Feature to A Macro

In order to pass a featureto a Macro it is necessary to define in the macro declaration that the argument is a feature using the "'" in the declaration and, when calling the Macro, use the "(" and ")" to inform that the feature has been passed.
In the Macro the feature is passed as object, so it can be access directly.
$$ Example of a MACRO Used with Feature passed directly
F(P1)=FEAT/POINT,CART,0,0,0,0,0,1

M(PASSING_A_FEATURE)=MACRO/'FEATURE'

DECL/LOCAL,DOUBLE, XX

XX=OBTAIN/F(FEATURE),3

tmpString=ASSIGN/CONCAT('The X VALUE OF THE PASSED POINT IS: ',STR(XX))

TEXT/OPER,tmpString

ENDMAC

CALL/M(PASSING_A_FEATURE),(P1)

Passing Feature to A Macro Using a Variable

In order to pass a feature to a Macro using a Variable it is necessary to define in the macro declaration that the argument is a Variable (see above) and, when using the Macro, use the "@" to access to the feature as variable:

$$ Example of a MACRO Used with Feature passed as Varible


F(P1)=FEAT/POINT,CART,0,0,0,0,0,1

M(PASSING_A_FEATURE)=MACRO/FEATURE

DECL/LOCAL,DOUBLE, XX

XX=OBTAIN/F(@FEATURE),3

tmpString=ASSIGN/CONCAT('The X VALUE OF THE PASSED POINT IS: ',STR(XX))

TEXT/OPER,tmpString

ENDMAC

CALL/M(PASSING_A_FEATURE),'P1'

Passing Features and Variables to A Macro Using a Variable

A macro can receive as arguments both features and Variables.

In this case it is necessary to define in the macro declaration that the argument is a Variable or a Feature (see above) and, when using the Macro, use the "@" or "(" and ")" to access to the feature or variable:

$$ Example of a MACRO Used with Feature passed as Varible


F(P1)=FEAT/POINT,CART,0,0,0,0,0,1
F(P2)=FEAT/POINT,CART,1,0,0,0,0,1


M(PASSING_A_FEATURE_AND_A_VARIABLE)=MACRO/'FEATURE_DIRECT',FEATURE_AS_VARIABLE,MYVARIABLE

DECL/LOCAL,DOUBLE, XX

DECL/LOCAL,DOUBLE, XX1

XX=OBTAIN/F(FEATURE_DIRECT),3

XX1=OBTAIN/F(@FEATURE_AS_VARIABLE),3

tmpString=ASSIGN/CONCAT('The X VALUE OF THE POINT PASSED DIRECTLY IS: ',STR(XX))

<code> TEXT/OPER,tmpString

tmpString=ASSIGN/CONCAT('The X VALUE OF THE POINT PASSED WITH VARIABLE IS: ',STR(XX1))

TEXT/OPER,tmpString

tmpString=ASSIGN/CONCAT('The Variable Passed is: ',STR(MYVARIABLE))


TEXT/OPER,tmpString

ENDMAC

CALL/M(PASSING_A_FEATURE),(P1),'P2',100
