[gradsusr] if else statement

[Rupak Rajbhandari]

Hi,

What exactly is the value when t=5? According to your example, it is an
error and the if condition is never true or less than -99999. According to
your example

d var(t=5)
Display error: there is no value
Try comparing with exact value when t=5; in this case it is "there"

val=subwrd(result,3)
if (val = 'there')
pp=99999
else
pp=val
endif
