Thats Mathcad!
As I have tried to tell you - you are using the wrong tool for what you are doing (whatever this may be).
Here you used a wrong syntax - you should not create a program to get a second line. Simply press the same shortcut you pressed the first time to get the symbolic eval.
If you use the correct syntax, Mathcad is not able to find a solution if you assume that m is integer, but it finds out that m has to be any integer if you assume that m is real.
Thats crazy and useless, but again - wrong tool.
Or the other way round - wrong task for an otherwise good tool.
Notice that using the correct syntax the vertical bar is much thinner.
