Quick question prototyping : dummies guide.

I wanted to know more about the D spec OPTIONS ( *VARSIZE )
So I coded this simple example to pass a shorter length parameter to my procedure than expected by that procedure.

I haven't achtually put the *VARSIZE in yet. My question is, why does my pgm compile as I am passing a shorter length parameter?
What difference will it make if I add *VARSIZE ?


D gPr1 S 1

D gPr2 S 50

D ChgPr PR

D P1 50 CONST

D P2 50

/FREE

gPr1 = 'S';

ChgPr ( gPr1 : gPr2 );

/END-FREE

P chgPr B

D PI

D APrIn 50 CONST

D APrOut 50

/FREE

APrOut = APrIn;

/END-FREE

P chgPr E
