Title: ScriptBasic Arrays
Post by: John Spikowski on March 15, 2025, 09:23:55 PM

One of the best features of ScriptBasic is its array support. ScriptBasic supports index, associative and a combinations of both. There isn't a practical limitation with indices / levels or do arrays need to be predefined. The following example shows these features.

• JSON to a multi-level associative array
• Adding a new element to the arryay
• Displaying the array in a readable format
• Using the UBOUND() function to get quantity

Code: Script BASIC

1. IMPORT webext.bas
2.  
3. json = """{"id":"0001","type":"donut","name":"Cake","ppu":0.55,"batters":{"batter":[{"id":"1001","type":"Regular"},{"id":"1002","type":"Chocolate"},{"id":"1003","type":"Blueberry"},{"id":"1004","type":"Devil's Food"}]},"topping":[{"id":"5001","type":"None"},{"id":"5002","type":"Glazed"},{"id":"5005","type":"Sugar"},{"id":"5007","type":"Powdered Sugar"},{"id":"5006","type":"Chocolate with Sprinkles"},{"id":"5003","type":"Chocolate"},{"id":"5004","type":"Maple"}]}"""
4.  
5. web::json2sba(json)
6.  
7. json{"topping"}{8}{"id"} = "5008"
8. json{"topping"}{8}{"type"} = "Cherry"
9.  
10.  
11. web::sbadump(json)
12. PRINT "\n\n"
13. PRINT "Number of batter items:  ", (UBOUND(json{"batters"}{"batter"}) + 1) / 2, "\n"
14. PRINT "Number of topping items: ", (UBOUND(json{"topping"}) + 1) / 2, "\n\n"
