Hello Stefan,
Thanks for the pointers. I have tried with a small section of scripting:
// Test script to launch and process GMT commands
dos('grd2xyz FAA.grd -ZTLa -V > faa.txt','-echo') // works fine
dos('grdinfo FAA.grd','-echo') // works fine
dos('grdinfo FAA.grd -C | gawk "{nx=$10; ny=$11}; {print nx, ny}" >
nxy.txt','-echo') // error
The third line fails with an error (gawk is in the PATH), perhas due
to the piping (|) or some other issue:
dos('grdinfo FAA.grd -C | gawk "{nx=$10; ny=$11}; {print nx, ny}" >
nxy.txt','-echo')
!--error 3
Waiting for right parenthesis.
at line 4 of exec file called by :
exec('C:\SS20-work\FAA_EAfrica\test_faa.sce', -1)
Are there limitations with this route?
Thanks
Lester
