[gradsusr] help Using Mathematical Function

[Heiner Körnich]

Hej Joao,

I think the problem is that the log-function is defined within the
grads-commands, but not within the script-commands, ie. you can use it in a
script within two apostrophes but not without.

Try this:
'd log('pres')'
logpp=subwrd(result,4)

result is a script variable which contains the output from the
grads-command. it looks like:
Result value = 4.60517
 The subwrd picks the 4th word of "result"

Regards till Johannes!

Cheers,
Heiner
