[gradsusr] display problem while saving

[Eric Altshuler]

This can be done more elegantly, as follows:

mons='jan feb mar apr may jun jul aug sep oct nov dec'
n=1
while (n<=12)
mmm=subwrd(mons,n)
...
...
n=n+1
endwhile

thus eliminating the need for 12 different 'if/endif' structures.

Jeevan,

The problem is with the time definision

There two way of defining time

set t 1

or

set time 01jan2010

Your variable mmm is now having integer value. You have to convert it
into three letter string. For that use the following code

n=m1
if(n=1) mmm='jan'
endif if(n=2)
mmm='feb' endif
if(n=3) mmm='mar'
endif if(n=4)
mmm='apr' endif
if(n=5) mmm='may'
endif if(n=6)
mmm='jun' endif
if(n=7) mmm='jul'
endif if(n=8)
mmm='aug' endif
if(n=9) mmm='sep'
endif if(n=10)
mmm='oct' endif
if(n=11) mmm='nov'
endif if(n=12)
mmm='dec' endif

then you can use format

'set time = 'dd''mmm''yyyy

Refine your code and try.

Regards
