# Re: st: problem with nlsur quaids

```In the line

scalar `l13' = -`l1' - `l2' - `l3'- `l4'- `l5'- `l6'- `l7'- `l8'-
`l9'- `l10'- `l11-`l12'

you have omitted an ' and in the line

replace `w9' = `a9' + `g91'*`lnp1' + `g92'*`lnp2' +
`g93'*`lnp3' +   ///
`g94'*`lnp4' + `g95'*`lnp5'+
`g96'*`lnp6'+ `g97'*`lnp7' + ///
`g98'*`lnp8' + `g99'*`lnp9'+
`g910'*`lnp10'+ `g911'*`lnp11' + ///
`g912'*`lnp12''+ `g913'*`lnp13'+
`b9'*(`lnexp'-`lnpindex')+
`l9'/`bofp'*(`lnexp' - `lnpindex')^2

you have one too many.

There are I think other such problems in your file: see -hexdump- for
a command that counts characters such as ` and '.

Your naming practices could bite you. Does 113 mean 11,3 or 1,13? If
you have indexes >9 it is best to use 11_3 and 1_13 to distinguish.
