7.2 Defining an array
● Access mode example 4:
The search concept is in Z. S contains the column index of the column in which concept is
being searched for. The line index of the concept found is output:
VAR1 = Thread[0.125,1,4]
Explanation:
Search for value 0.125 in column 1 of array "Thread" and transfer the line index of the value
found to VAR1.
● Access mode example 5:
Z contains the line index of line in which concept is being searched for. The search concept
is in S. The column index of the concept found is output:
VAR1 = Thread[4,0.2,5,1]
Explanation:
Search in line 4 of the "Thread" array for the value 0.2 and transfer the column index of the
value found to VAR1. Comparison mode 1 was selected because the values of line 4 are
not sorted in ascending order.

Parameters:
Return Value:
Example
DEF MPIT = (R///"MPIT",,"MPIT",""/wr3)
DEF PIT
PRESS(VS1)
MPIT = 0.6
IF MET_G[MPIT,0,4,1].VLD == TRUE
ELSE
200
Identifier [Z, S, [M[,C]]] .vld
Status is a read-only property.
Identifier
= (R///"PIT",,"PIT",""/wr3)
PIT = MET_G[MPIT,1,0].VAL
REG[4] = PIT
REG[1] = "OK"
REG[1] = "ERROR"
;VAR1 has the value 2
;VAR1 has the value 1
Name of array
FALSE = invalid value
TRUE = valid value
