PRIORITY$

System variable: PRIORITY$
Length: 1
Description: The system variable named PRIORITY$ is a one-byte string with a value ranging from "00" hex to "FF" hex. The value of PRIORITY$ represents the number of task breaks Comet will skip before reactivating the task. The higher the number, the slower this program will run relative to other programs. PRIORITY$ can be interrogated and set by an MTB program.
Example 1: 
A=HEXDEC(PRIORITY$)
This example shows how to interrogate the system variable named PRIORITY$. In this example, the priority value is converted to decimal and moved to a numeric variable named A.
Example 2: 
PRINT (0) "ENTER NEW PRIORITY (0 - 255):"
INPUT (0) VALUE
PRIORITY$ = DECHEX(VALUE,ERR)
This example shows how to set the PRIORITY$ value. In this program segment, the user is prompted for a new priority value. The number is entered in decimal form, converted to hex, and assigned to the system variable named PRIORITY$.
