## Manual page for mcrl2i¶

### Usage¶

mcrl2i   [OPTION]... [INFILE]


### Description¶

Evaluate mCRL2 data expressions via a text-based interface. If INFILE is present and if it contains an LPS or PBES, the data types of this specification may be used. If no input file is given, only the standard numeric datatypes are available. Stdin is ignored.The following commands are available to manipulate mcrl2 data expressions. Essentially, there are commands to rewrite and type expressions, as well as generating the solutions for a boolean expression. The expressions can contain assigned or unassigned variables. Note that there are no bounds on the number of steps to evaluate or solve an expression, nor is the number of solutions bounded. Hence, the assign, eval solve commands can give rise to infinite loops.

h[elp] print this help message. q[uit] quit. t[ype] EXPRESSION print type of EXPRESSION. a[ssign] VAR=EXPRESSION evaluate the expression and assign it to the variable. e[val] EXPRESSION rewrite EXPRESSION and print result. v[ar] VARLIST declare variables in VARLIST. r[ewriter] STRATEGY use STRATEGY for rewriting. s[solve] VARLIST. EXPRESSION give all valuations of the variables in

VARLIST that satisfy EXPRESSION.

VARLIST is of the form x,y,...: S; ... v,w,...: T.

### Command line options¶
