Hey,
how can i do this LIKE '[^A-D][^A-Z][^A-Z][^0-9]%' in SAS?
I want to leave only those cases that do not have the letters A to D in the first place, the letters A to Z in the second and third places and the numbers 0 to 1 in the fourth place.
Sample data below:

FU321007
18AC90104
ACZ879876
15BA10226
18AC77472
CSR646689
AA9601648
AAA655447

Hi and welcome to the SAS Community.

You can do something like this

data have;
input string $10.;
datalines;
FU321007
18AC90104
ACZ879876
15BA10226
18AC77472
CSR646689
AA9601648
AAA655447
;

data want;
    set have;
    if not prxmatch('/^[A-D][A-Z]{2}[0-9]/', string);
run;

index or substr functions with an "if ... then delete" statement. That would be a crude way, i think there's a better way using other text functions that someone else will know
