[gradsusr] Error opening .txt file in a grads script

[Keren Rosado - NOAA Affiliate]

Hello,

I am trying to open a .txt file in a .gs grads script without luck.
Grads version 2.0.1


This is what I have

'open dummy.ctl'
file = 'A20100826a.txt'
colors="1 2 3 4 5 6 7 8 9 10 11 12 13"
ccount=0

rc=1
while (rc != 2)
   data=read(file)
   rc=sublin(data,1)
   if (rc != 2)
      line=sublin(data,2)
      chk=substr(line,1,10)
      if (chk != "----------")
.
.
.
.
 The code keeps going but the error is at the "file" line.

Here is the error
file = 'A20100826a.txt'
Syntax Error:  Expected operand or '('
  Error ocurred at column 1
DEFINE error:  Invalid expression.

Thanks!
