function call is some how retaining previous call values in SKILL

RFStuff

 Dear All,

I am calling function as below:-

       guardring(L_cell W_cell clearance W_guard Space_NTAP_PATAP First_type_tap).

      When I call second time this function in CIW, it some how retaining the previous call vlaues. So the outcome result is wrong.

       However when I call it 2nd time it gives me dsired result. It looks like the variable is NOT prempted after function call is over.

   Can anybody please tell why it happening. It looks like to me a file open/close problem.

My code is as below:

procedure( guardring(L_cell W_cell clearance W_guard Space_NTAP_PATAP First_type_tap)
xPitch=0.16+0.2
yPitch=0.16+0.2
;row=5
;column=20

    if( (First_type_tap=="N") then

        ; For Creating  NTAP
         
            NTAP_CONT_NO_IN_THICKNESS=car(guardtapsize( (W_guard+0.64) "NTAP" ))
                printf("NTAP_CONT_NO_IN_THICKNESS=%d",NTAP_CONT_NO_IN_THICKNESS)
            NTAP_THICKNESS= (NTAP_CONT_NO_IN_THICKNESS*0.36) +0.56
            printf("NTAP_THICKNESS=%f\n",NTAP_THICKNESS)
            NTAP_LENGTH=(2*(NTAP_THICKNESS+clearance))+L_cell
            NTAP_CONT_NO_IN_LENGTH=car(guardtapsize( NTAP_LENGTH "NTAP" ))
            NTAP_LENGTH= (NTAP_CONT_NO_IN_LENGTH*0.36) +0.56
            printf("NTAP_LENGTH=%f",NTAP_LENGTH)
            row=NTAP_CONT_NO_IN_THICKNESS
            column=NTAP_CONT_NO_IN_LENGTH
            xOffset=0
            yOffset=0
        guardlayercreate( "NTAP" xPitch yPitch row column xOffset yOffset "Y" )
           ...................................................................



 ....................................................................

) /*End of procedure*/  

procedure( guardtapsize( width type )
             ;declare(a[2])
             if( (type=="NTAP") then

               
             N_width=  ceiling(((width-0.56)/0.36))
             ;actual_width=( (N_width*0.36) +0.56)
                 printf("N_width=%d\n",N_width)
                     ;printf("actual_width=%f\n",actual_width)
                     ;a[0]=N_width
                     ;a[1]=actual_width
            else
                     
              N_width=  ceiling(((width-0.24)/0.36))
              ;actual_width=( (N_width*0.36) +0.24)
                      printf("N_width=%d\n",N_width)
                  ;printf("actual_width=%f\n",actual_width)
                      ;a[0]=N_width
                      ;a[1]=actual_width
             )
               list(N_width)    
          )

    Dear Andrew,

    Sorry, I did some mistakes in the code. After fixing them the issue got resolved though it was not pertaing to Global/Local variable type.

    Since you have pointed out about the variable types, it creats some ambiguities for me.

    1) : It looks like SKILL does not require special command for Global variables rather it requires for loacal variable

          Suppose a function is as follows:

                    procedure( funct(x,y))


                        a=x

                       b=y

                      c=a+b

                   )

                c is a global variable.

              After calling this function in CIW funct(2,3), if I type a= , I should get a=2, if I type c= , I should get c=5

             But I am NOT getting it

    2)   SKILL Lint in the SKILL Development Tools (from the CIW Tools menu) has many options, is tere any document which tells how to use it

    Kind Regards
