LET and SET redefined

[deepali_more]

Hello,

i know the difference between Let & Set keywords.but i have a scenario where in i have defined a variable using Set Keword but i waant to evaluate the string in that variable. How this can be achieved?

Hi,

Like this.?

SET v1   =  '4+5';

LET v2   = Evaluate(v1);

[Gysbert_Wassenaar]

Dollar expand it: LET vMySecondVar = $(vMyFirstVar);

... or even simpler: Don't dollar-expand it.

Let vMySecondVar = vMyFirstVar;

Set vMyFirstVar = 5+6;

Let vMySecondVar = vMyFirstVar;

vMySecondVar  doesn't seem to evaluate the string, it returns the string as it is.

In that case vMySecondVar  would required to be dollar-expanded, right?

[hic]

You're right. I missed that. Evaluate or dollar expansion will both store 9 in the second variable, whereas the plain Let will store 4+5.
