Multifunction alias
 
Am trying to setup a useful alias script that sends me to a relevant potion vendor to purchase items dependent on character level.

Code:
#IF (%2 < 1) {$num=1} {#MATH $num %2*30}

#SWITCH (%1)
  ("heal") {
    #SWITCH (@curlev)
      (<20) {#WALK aeler;#VAR hl "light relief";buy $num @hl;pc all.'@hl'}
      (<40) {#WALK aeler;#VAR hl "serious relief";buy $num @hl;pc all.'@hl'}
      (<60) {#WALK aeler;#VAR hl "critical care";buy $num @hl;pc all.'@hl'}
      {#WALK duff;#VAR hl "duff";buy $num @hl;pc all.'@hl'}
  }
  ("ref") {
    #SWITCH (@curlev)
      (<50) {#WALK aeler;#VAR rf "green tea";buy $num @rf;pc all.'@rf'}
      (<90) {#WALK pharm;#VAR rf "divine";buy $num @rf;pc all.'@rf'}
      {#WALK duff;#VAR rf "moonshine";buy $num @rf;pc all.'@rf'}
  }
  ("mana") {
    #SWITCH (@curlev)
      (<30) {#WALK aeler;#VAR mn "rush";buy $num @mn;pc all.'@mn'}
      (<50) {#WALK pharm;#VAR mn "beads";buy $num @mn;pc all.'@mn'}
      (<90) {#WALK duff;#VAR mn "tequila";buy $num @mn;pc all.'@mn'}
      {#WALK duff;#VAR mn "vodka";buy $num @mn;pc all.'@mn'}
  }


Am getting

ERROR: Syntax error in Alias: shop2 : illegal character in expression: <

As the error function gives no line number, I can only assume it is the first instance. If so, how do I test for the alias parameter being less than a specific value?

You can't use #SWITCH in that manner unless you are testing against a static value, like in the outer #SWITCH, if you want to compare the value in the nested #SWITCHes you need more explicit expressions:

Code:
#SWITCH (@curlev<30) {#WALK aeler;#VAR mn "rush";buy $num @mn;pc all.'@mn'}
      (@curlev<50) {#WALK pharm;#VAR mn "beads";buy $num @mn;pc all.'@mn'}
      (@curlev<90) {#WALK duff;#VAR mn "tequila";buy $num @mn;pc all.'@mn'}
      {#WALK duff;#VAR mn "vodka";buy $num @mn;pc all.'@mn'}

Thanks. I had it that way originally but some other error prompted me to alter it (just in case , or to simplify the code).

Now it functions. I had to go with a permanent count (num) variable as there appeared to be issues with the scope of the local variable that I couldn't easily pin down (but that may have been complicated by other errors)..

I am also thinking of using an indirect reference to the potion vars (rf, mn, hl, etc) to make a simpler version, such as:

buy @num @potion;pc all.@potion

and have @potion be one of @hl, @mn, @rf, etc

Code:
#VAR num
#IF (%2<1) {num=30} {#MATH num 30*%2}

#SWITCH (%1)
  ("fly") {#WALK aeler;#VAR fly "blood";buy @num @fly;pc all.@fly}
 
  ("heal") {
    #SWITCH (@curlev<20) {#WALK aeler;#VAR hl "relief";buy @num @hl;pc all.@hl}
      (@curlev<40) {#WALK aeler;#VAR hl "serious";buy @num @hl;pc all.@hl}
      (@curlev<60) {#WALK aeler;#VAR hl "critical";buy;@num @hl;pc all.@hl}
      {#WALK duff;#VAR hl "duff";buy @num @hl;pc all.@hl}
  }
 
  ("mana") {
    #SWITCH (@curlev<30) {#WALK aeler;#VAR mn "rush";buy @num @mn;pc all.@mn}
      (@curlev<50) {#WALK pharm;#VAR mn "beads";buy @num @mn;pc all.@mn}
      (@curlev<90) {#WALK duff;#VAR mn "tequila";buy @num @mn;pc all.@mn}
      {#WALK duff;#VAR mn "vodka";buy @num @mn;pc all.@mn}
  }
 
  ("ref") {
    #SWITCH (@curlev<50) {#WALK aeler;#VAR rf "tea";buy @num @rf;pc all.@rf}
      (@curlev<90) {#WALK pharm;#VAR rf "divine";buy @num @rf;pc all.@rf}
      {#WALK duff;#VAR rf "moonshine";buy @num @rf;pc all.@rf}
  }

because it was defined within the #IF, it dies in the #IF unless you initialize it BEFORE the #IF.

#LOCAL $num
#IF (%2<1) {$num=30} {$num=(30*%2)}

For the indirect issue... does all.@var even work? I would use something like:

#FORALL @potion {pc %i}
