Bingo!  It finally works.  Thank you.  Below is the cleaned up sequence that works and the if() removed from the for() loop. 

Question:  As with PrfTrace here, does PrfTrace need to be initialized before it can be populated in other sequences, or can it just be declared and populated later?

Startup:

global TmpStart = 82
global PrfTrace
PrfTrace[11][1] = 0
global Profile
Profile = {{3,95,2},{4,120,3},{2,129,3},{5,90,1}}

SetValues sequence:

private ElapseTime = 0
PrfTrace[0][0] = 0
PrfTrace[0][1] = TmpStart
for(private i = 0, i < NumRows(Profile), i++)
   ElapseTime = ElapseTime + Profile[i][0]
   PrfTrace[(2*i)+1][0] = ElapseTime
   PrfTrace[(2*i)+1][1] = Profile[i][1]
   ElapseTime = ElapseTime + Profile[i][2]
   PrfTrace[(2*i)+2][0] = ElapseTime   
   PrfTrace[(2*i)+2][1] = Profile[i][1]
endfor

I see what your saying.  My rework, as shown below, still yields a C1070 error at line 3.  I'm guessing I still have an initialization issue.

Startup:

global TmpStart = 82
global PrfTrace
PrfTrace[11][1] = 0
global Profile
Profile = {{3,95,2},{4,120,3},{2,129,3},{5,90,1}}

Setup 2-column array from a 3-column array:

private ElapseTime = 0
for(private i = 0, i < NumRows(Profile), i++)
   if(i = 0)
      PrfTrace[0][0] = 0
      PrfTrace[0][1] = TmpStart
   endif
   ElapseTime = ElapseTime + Profile[i][0]
   PrfTrace[(2*i)+1][0] = ElapseTime
   PrfTrace[(2*i)+1][1] = Profile[i][1]
   ElapseTime = ElapseTime + Profile[i][2]
   PrfTrace[(2*i)+2][0] = ElapseTime   
   PrfTrace[(2*i)+2][1] = Profile[i][1]
endfor

I think I made the changes you suggested as shown below.  I'm still getting error C1086 at line 7

Startup sequence:

// set Global Variables
global TmpMax = 140
global TmpMin = 80
global TmpStart = 82
global PrfTrace
global Profile
Profile = {{3,95,2},{4,120,3},{2,129,3},{5,90,1}}

SetProfileValues sequence:

private ElapseTime = 0
private cnt = (2 * (NumRows(Profile))) + 1
PrfTrace[0][0] = TmpStart
PrfTrace[0][1] = 0
for(private i = 1, i < cnt, i = i+2)
   PrfTrace[i][0] = Profile[i-1][1]
   ElapseTime = ElapseTime + Profile[i-1][0]
   PrfTrace[i][1] = ElapseTime   
   PrfTrace[i+1][0] = Profile[i-1][1]
   ElapseTime = ElapseTime + Profile[i-1][2]
   PrfTrace[i+1][1] = ElapseTime
endfor

OH.  I have also declared Steps in the Startup sequence,

global Steps = 4

This is a test sequence for moving a time/temperature array (Profile) into an array (PrfTrace) to be used in graphing the profile.  However, I get an error message (C1086) at line 7.

These first declarations are in the Startup sequence:

global Profile[12,3] = {{3,95,2},{4,120,3},{2,129,3},{5,90,1}}
global TmpStart = 82
global PrfTrace[12,2]

Sequence: SetProfileValues:

private ElapseTime = 0
private cnt = (2*Steps)+1
PrfTrace[0][0] = TmpStart
PrfTrace[0][1] = 20
for(private i=1, i<cnt, i=i+2)
   PrfTrace[i][0] = Profile[i-1][1]
   ElapseTime = ElapseTime + Profile[i-1][0]
   PrfTrace[i][1] = ElapseTime   
   PrfTrace[i+1][0] = Profile[i-1][1]
   ElapseTime = ElapseTime + Profile[i-1][2]
   PrfTrace[i+1][1] = ElapseTime
endfor
