Scale Basic 4.2E Reference
Flag on, 1 turn on flag 1
Display Memory1 set to display Memory1 (total)
End if End if
End End of function
If not (condition) / Else / End if 242 [nnn] / 251 / 240
Purpose: to control program flow using a condition code.
Remarks: sometimes it is more meaningful or more convenient to test for a false condition
rather than a true condition. In these situations, use the If not instruction.
Example:
If not, Centerz If the scale is not at center of zero
Gosub Zero Zero the scale
End if End if
Inc [r] 204 [r]
Purpose: add 1 to a register. Set condition codes Positive, Negative, and Zero to reflect results.
Remarks: the decimal point is ignored. If Memory1 = 0.05, then Inc Memory1 = 0.06 This
instruction is useful for counting the number of times something occurs.
Example:
Set, Memory1, 25 For loop count = 25
Loop1 Do
:
<Do loop stuff here>
:
Dec, Memory1 loop count = loop count - 1
If, Positive While loop count > 0
Next1 Next loop
End if End of For/Next loop
Index id [r] 217 [r]
Purpose: to access Id memory as an array of records. The register [r] opens records by their
location in memory.
Remarks: the Get id, Make id, Write id, Erase id instructions access Id memory with randomly
assigned Id numbers (the Id key). The Index id instruction accesses an Id record by it’s
location in memory. With this instruction you view Id memory as (approx.) 490 records: | ID
record 1 | ID record 2 | ID record 3 | ……. | ID record 490 |. The condition code Zero is set
true if the index number > maximum or register [r] does not exist.
NOTE: In EZ Link, the fields in an ID record are accessed via Id1, Id2, …. Do not confuse
the ID record with the Id field access symbols.
Example: access ID record 3, set Id register 1 to 0, save the change to ID record 3.
