Select - EndSl Problem ?

FLD1 is a hidden field.

'Following code works fine
EXFMT main
Select
When  FLD1='A' or FLD1='B' or FLD1='C'  <----- This line works but If I
break this line into 2 lines, it does not work, any idea please ?
exsr myproc
endsl

'Following code gives operand mismatch error
EXFMT main
Select
When  FLD1='A' or  +
FLD1='B' or +
FLD1='C'  <----- This line works but If I break this line into 2 lines, it
does not work, any idea please ?
exsr myproc
endsl

Any idea please ?
