catx with sysfunc

Hello everbody!!

Follow my doubt:

%let CPF = 15534556205;

%let Partic = 82;

%let condicao1 =  ID = &CPF;

%let condicao2 =  Partic = &Partic;

%put &condicao1;

%put &condicao2;

%let Todas = %sysfunc(catx(and ,&condicao1.,&condicao2.));

%put &Todas;

I wish I had the result "ID = 15534556205 and Partic 82.", but the variable macro &Todas return "0and0", I can understand why this happen.

tk's in advanced.

Re: catx with sysfunc

Evidently, when CATX sees the equal signs in the second and third parameters, it is treating them as logical comparisons and evaluating them.  Since "ID" is not equal to "155345562505", the comparison is false and the logical result is 0.  If you need convincing, try replacing the equal signs with the word "is":

%let condicao1 = ID is &CPF;

%let condicao2 = Partic is &Partic;

After that, the rest should work as expected.

The simplest remedy is to get rid of CATX entirely.  It would be easy enough to code:

%let Todas = &condacao1. and &condacao2.;

Good luck.
