You can use a regular expression to prompt the user that the alphanumeric text field only accepts alpha or numeric chars.

Example:

if not regexmatch(ALPHA_ONLY_FIELD, "^[a-zA-Z]+$") then
    errmsg("Field only accepts alpha characters");
    reenter;
endif;

if not regexmatch(NUMERIC_ONLY_FIELD, "^[0-9]+$") then
    errmsg("Field only accepts numeric characters");
    reenter;
endif;
