Finally i made an acronym replacer that uses regular expressions to do the job or checking and replacing acronyms. To use this alias follow the directions below.

;Regular Expression Acronym Replacer
;Script By: DarthReven
;-----------------------------------
;To use this addon add the alias to any "ON INPUT" event
;Then add each acronym in this format:
;/hadd REG_ACRO_TABLE <acronym> <acronym meening>
;EX: /hadd REG_ACRO_TABLE lol laughing out loud
;------------------------------------

alias REG_ACRO {
  VAR %REG_ACRO_INPUT $1-, %REG_ACRO_TOK $HGET(REG_ACRO_TABLE,0).DATA, %REG_ACRO_TEMP, %REG_ACRO_OUTPUT
  WHILE (%REG_ACRO_TOK) {
    IF ($REGEX(REG_ACRO_EX,%REG_ACRO_INPUT,$+(/\b,$CHR(40),$HGET(REG_ACRO_TABLE,%REG_ACRO_TOK).ITEM,$CHR(41),\b/ig))) {
      %REG_ACRO_TEMP = $REGSUB(%REG_ACRO_INPUT,$+(/\b,$CHR(40),$HGET(REG_ACRO_TABLE,%REG_ACRO_TOK).ITEM,$CHR(41),\b/ig),$HGET(REG_ACRO_TABLE,%REG_ACRO_TOK).DATA,%REG_ACRO_OUTPUT)
      %REG_ACRO_TEMP = $REGSUB(%REG_ACRO_OUTPUT,$+(/\b,$CHR(40),$HGET(REG_ACRO_TABLE,%REG_ACRO_TOK).ITEM,$CHR(41),\b/ig),$HGET(REG_ACRO_TABLE,%REG_ACRO_TOK).DATA,%REG_ACRO_INPUT)
    }
    DEC %REG_ACRO_TOK
  }
  TOKENIZE 32 $IIF(%REG_ACRO_OUTPUT,$v1,%REG_ACRO_INPUT)
  RETURN $+($UPPER($LEFT($1,1)),$MID($1-,2))
}
ON *:START: { hmake REG_ACRO_TABLE 1000 | hload REG_ACRO_TABLE REG_ACRO_TABLE.HSH }
ON *:EXIT: { hsave -o REG_ACRO_TABLE REG_ACRO_TABLE.HSH }
