Try if using parenthesis with multiline parts would help:

VB

if not ISNULL({invoice01.INAME}) then
    VarINAME := {invoice01.INAME};

if not ISNULL({invoice01.BATCHNO}) then
(
    if {invoice01.BATCHNO} <> "" then
    VarINAME := VarINAME + ' Batch:' + {invoice01.BATCHNO};
);

if not ISNULL({invoice01.EXPDATE}) then
    if year({invoice01.EXPDATE})>1970 then
        VarINAME := VarINAME + ' Exp:' + totext({invoice01.EXPDATE},"MMM yy");

I got solution for the problem. By adding an else clause, surprisingly it works.

SQL

Global StringVar VarINAME:="";

if not(ISNULL({invoice01.INAME})) then VarINAME := {invoice01.INAME}
else VarINAME := "";

if not (ISNULL({invoice01.BATCHNO})) then
(
    if {invoice01.BATCHNO} <> "" then
        VarINAME := VarINAME + '  Batch:' + {invoice01.BATCHNO}
    else VarINAME := VarINAME + "";
)
else VarINAME := VarINAME + "";


if not (ISNULL({invoice01.EXPDATE})) then
(
    if year({invoice01.EXPDATE})>1970 then
        VarINAME := VarINAME + '  Exp:' + totext({invoice01.EXPDATE},"MMM yy")
    else VarINAME := VarINAME + "";
)
else VarINAME := VarINAME + "";
