Merge Static and dynamic parts in variable declaration

Dear Unix experts

I want to define a variable which contains dynmic and static part, daynamic part is the first field.

Sample of data

dddd aaaa sssss 12345
ssss 2323 234234 4242
dddd 3223 34234 54353
ssss 24234 3434 42342
dddd rwrw 423423 werwer

Code:

nawk 'BEGIN {FS=" "}{ $1"_subs"=$1"_subs"+1}END {print dddd_subs}'

it should give me 3

but it gives me error "nawk: syntax error at source line 1
context is
BEGIN {FS=";"}{ >>> $1"_"subs= <<< $1"_"subs+1}
nawk: illegal statement at source line 1"

Can you please help ?
Many thanks in advance

I also tried

Code:

nawk 'BEGIN {FS=";"}{ subs[$1]=+1}END {print subs[dddd]}

but the results were always 1!!!!

ucblinks

ucblinks(1B)					     SunOS/BSD Compatibility Package Commands					      ucblinks(1B)

NAME
       ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices

SYNOPSIS
       /usr/ucb/ucblinks [-e rulebase] [-r rootdir]

DESCRIPTION
       ucblinks  creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi-
       ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry.

       ucblinks does not remove unneeded compatibility links; these must be removed by hand.

       ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been  created,
       since the reconfiguration may have resulted in more compatibility names being needed.

       In  releases prior to SunOS 5.4, ucblinks used a  nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses  nawk
       for the default operation, although  nawk rule-bases can still be specifed with the -e option.  The  nawk rule-base equivalent to the SunOS
       5.4 default operation can be found in /usr/ucblib/ucblinks.awk.

OPTIONS
       -e rulebase     Specify rulebase as the file containing nawk(1) pattern-action statements.

       -r rootdir      Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /.

FILES
       /usr/ucblib/ucblinks.awk        sample rule-base for compatibility links
