[gradsusr] writing some defined variables in ASCII file

[hachelaf rabah]

Hello Muhamed,
your script help me , but it doesn't work fine
i have this warning when i run it :
ga-> test.gs
Data Request Error:  File number out of range
  Variable = tdif0.00353409
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = tdif0.00353409
Data Request Error:  File number out of range
  Variable = sumxtdif1.84828
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = sumxtdif1.84828
Data Request Error:  File number out of range
  Variable = sumttdif663.954
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = sumttdif663.954
Data Request Error:  File number out of range
  Variable = eqmtr8500.173326
..............................
However i need to write just some variables from all screened by taping " q
define "
so i don't know who to filtered just desired variables.
