Check your typing for '$' designating variables. This is
also important when writing BASIC code. anum -> $anum

Check your typing for semi-colons. This is
also important when writing BASIC code. $num=anum -> $num=$anum;

Check 'type'-ing to see that you are not asking to concatenate numeric
variables onto character strings. Leading zero suppression is leading
zero suppression, regardless how many zeroes you put in front.
