Setting a variable ( en )

Last modification : 2013/01/26 19:16
To set a variable the syntax is: set name = value.

In MSH.EXE all variables are global (available everywhere in the script). There is no type: all variables are string typed. Conversions are made automatically depending on the calling function (see expr).

The set internal command can be forgotten. These commands are both valid: 
msh> A=MAJOR
msh> set a=minor
msh> print $A $a
MAJOR minor
If the variable name does not exists the variable is created, and it is updated otherwise. 
msh> print $A
 
msh> A=123
msh> print $A
123
msh> A=456
msh> print $A
456
