[gradsusr] if else statement

[Manoranjan LPAS]

Dear users,
Sorry!! I am not able to do it. Part of my grads output looks as:

d var(t=1)
printing value 89
d var(t=2)
printing value 77
d var(t=3)
printing value 85
d var(t=4)
printing value 79
d var(t=5)
Display error: there is no value
d var(t=6)
printing value 81
d var(t=7)
printing value 88

I would like to write these grads output values in ACSII format as:
89
77
85
79
99999
81
88

I tried with the following, but it is giving all the values 99999.
t1=1
t2=7
while(t1<=t2)
set t 't1
 'd 'var''
val=subwrd(result,3)
if (val < -99999)
pp=99999
else
pp=val
endif
rc=write(outfile.txt,pp)
t1=t1+1
endwhile

I sincerely appreciate, in advance, for any kind of help or suggestion in
this regard.

Thank you Rupak for your suggestion, but that doesn't work.

Mano
