Question

I want to run an if else on base of a commandfield on each row,

For example

 If {CommandField=0} Update counter by 1 return counter

 else if {CommandField=1} return 'Reporting'

I tried it but having error

     stringVar layerType; 
shared numberVar layNo;

     if({Command.ISREPORT}=0) then
           layNo:=layNo+1;layerType:=layNo;layerType

     else if ({Command.ISREPORT}=1) then
      layerType:='Reporting'; layerType

results should be like

ISREPORT   LayerNo
   0         1
   0         2 
   0         3
   0         4
   1       'Reporter' 

Answer 1

Not sure I understand but is this right:

stringVar layerType; 
shared numberVar layNo;

     if({Command.ISREPORT}=0) then
     (     layNo:=layNo+1;
           layerType:=ToText(layNo);
           layerType;
     )
     else 
     (  if ({Command.ISREPORT}=1) then
           layerType:='Reporting'; 
           layerType
     )

…which can be simplified to this:

shared numberVar layNo;

     if({Command.ISREPORT}=0) then
     (     
           layNo:=layNo+1;
           ToText(layNo);
     )
     else 
     (if ({Command.ISREPORT}=1) then
           'Reporting';)

..assuming the value of ISREPORT can only be 0 or 1 then we can further simplify to this:

shared numberVar layNo;

     if({Command.ISREPORT}=0) then
     (     
           layNo:=layNo+1;
           ToText(layNo);
     )
     else
     (
       layNo:=0;
       'Reporting';
     )

Update – I’ve changed the last example to reset the counter on ‘reporting’.

Edit:
change the ToText(.. to this ToText(layNo,0); (sets decimal places to zero)
