How to create a global array in netlogo -


i trying create array can accessed of patches, seems though setting global, available in function in gave value. have following 3 segments of code in respective places:

globals[a]

toward top of program, in setup function have

set array:from-list n-values asize [0]

for integer asize defined in setup function, , go method calls function addtoarr runs following line:

array:set index val

for index , val defined earlier in function. might worth noting within ask patches. when run code following error:

extension exception: not array: 0 error while patch 70 91 running array:set called procedure addtoarr called procedure go called button 'go-forever'

i confused error, because seems me defined a array, netlogo differs in opinion. netlogo not support global arrays? appreciated.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
